Through terminal - Which feed-through terminals should you use for your control cabinet? Are terminal blocks the same as feed-through blocks? Find out here what the differences are between feed-through terminals and what they are used for. In the eibabo® technology store you can get feed-through terminal blocks from all well-known manufacturers such as ABB, Eaton, Eberle, Hager, Metz, Phoenix, Schneider Electric, Siemens, Spelsberg, TE Connectivity, WAGO, Weidmüller, Wieland and Wöhner at great prices and in large quantities. We deliver our range worldwide.Feed-through terminals fulfill several functions and are among the most important components within a control cabinet. It is mounted on the DIN rail. Feed-through terminals are connecting elements between the incoming cables and lines of an installation and the actual control cabinet installation.What is the difference between feed-through terminals and terminal blocks?Feed-through terminals are terminal blocks. 'Terminal block' is a generic term that also includes other types of terminals. These include, for example, fuse terminals and relay terminals. Other terms describe the way a terminal is constructed or its ability to connect the conductors. In these contexts, one often hears about one-tier terminals, three-tier terminals, spring-loaded terminals, push-in terminals or screw terminals. We would like to briefly discuss some of these types in the following sections.Why are feed-through terminals indispensable components in the control cabinet?Feed-through terminals offer the necessary flexibility in the control cabinet to connect rigid incoming cables and lines to the relevant fuses, actuators or other devices. A direct connection without feed-through terminals does not make sense. A clear installation would not be possible. First, the cables and lines are clearly laid out on the terminal blocks. They then lead them from there to the devices in the control cabinet. As a result, the entire installation remains flexible because there are connection points and nodes for checking and changing the system structure.Image: Phoenix PT 2.5-3L feed-through terminalEach connection that is made takes on a function previously defined in the circuit diagram. The installation of the system and the function of individual connections remains traceable. This makes later additions, repairs and maintenance easier. If you want to make changes, these can be done by reconnecting individual wires. The rigid supply lines remain unaffected.And there are other advantages: For example, you can only connect two wires to many modular installation devices. The feed-through terminal blocks offer further advantages here. An example: A fuse is intended to protect several lines. However, you can only connect the cores of one line. In order to also integrate the other lines, you can create clear bridge connections on the feed-through terminals. The electrician can also carry out insulation measurements and other control work directly on the terminal blocks. Troubleshooting is made much easier and faster.What different feed-through terminals are there?Each manufacturer builds the feed-through terminals slightly differently. However, the principle is the same. There are single-level terminals and multi-level terminals. While you can only connect one line in the single-level terminal, several incoming and outgoing lines can be installed in multi-level terminals. Use a three-tier terminal for a three-wire cable. The is designed for connecting the protective conductor, the L conductor and the N conductor. This arrangement saves an enormous amount of space in the control cabinet. Three-tier terminals are mainly found in the control cabinets of private households and in smart home installations. TIP:On some models, the protective conductor has no connection point for the outgoing line. The protective earth contact is made directly by the clamp connection with the DIN rail. Another feature that distinguishes feed-through terminals is the way the wires are fastened. The screw terminal fixes the respective wire with a screw connection. This method takes a comparatively long time, especially when the plant is complex. A spring-loaded terminal makes electrical contact with a mechanical spring. This consists of a bent, flat copper contact. The wire must be inserted through a hole in the copper contact. This is only possible if the contact is clamped with a pointed tool. When the clamping tool is removed, the spring pulls back and the wire is jammed. The connection is released in the same way. The push-in connection is another fastening variant, similar to the spring-loaded terminal. Here, too, a spring presses against the wire. In contrast to the spring-cage connection, installation is tool-free and therefore even faster. The wire is inserted into the spring shaft of the feed-through terminal and the spring locks automatically. If you want to loosen the connection, you need a pointed tool. A small screwdriver is usually sufficient, which bends the retaining spring to the side and loosens the wire. This method saves a lot of time with cores with solid conductors. Wires with flexible conductors can also be attached using wire end sleeves using this method.Solid and flexible veinsYou can connect cables with solid cores and flexible strands in feed-through terminals. Both variants and combinations are permitted. Flexible cores can easily fan out. The use of ferrules makes handling easier with spring connections.The attachment of the wire using cutting terminals is rather rare. Use this variant if your veins are particularly thin. Here, the contact is made through a small cut in the insulation.Depending on the function and area of application, cables and wires with different cross-sections are used in the electrical installation. This affects the feed-through terminals. Appropriate feed-through terminals are available for all common cable cross-sections. Whether a clamp can be used for a specific cross-section is indicated on the clamp. It is usually possible to bridge the L conductor and the N conductor using several feed-through terminals, sometimes on several levels. Suitable cable bridges are available here in the shop.markLabeling the lines helps with orientation, especially when a new employee or another electrical company takes over the system. Some terminals have labeling fields. We recommend using this option and labeling all devices and connections in a meaningful way.The design of the neutral conductor contact is another distinguishing feature. In addition to models for classic wiring, there are feed-through terminals with which an N busbar can be used. The neutral contact on these terminals is designed accordingly so that the connection can be made with one hand. When using a busbar, you need an additional terminal for feeding. To securely fix the rail, use suitable support blocks or the fastening levers on the end clamps at the beginning and end of the row. Longer rails are additionally fixed every 20 cm. To be able to use cables with five cores, use multi-level terminals to connect the outer conductors.How to use feed-through terminals in the KNX area?In addition to the classic feed-through terminals, you can get special terminal blocks for low-voltage or KNX use. These have a different color and can therefore immediately be distinguished from other terminal blocks. This also contributes to order and clarity in the control cabinet. In terms of function, these terminal blocks hardly differ from conventional terminal blocks. You can connect cables with a cross-section of up to 1.5 mm2 to these terminals.Why are feed-through terminals not closed on one side?The available space in the control cabinet is specified in modular widths (HP). These provide information about the capacity of a control cabinet. Feed-through terminals are not manufactured according to this pitch, but as narrow as possible. The narrower a terminal, the more terminals can be installed on a specific area of the DIN rail. Good to know:Feed-through terminals are not closed on one side. The missing cover saves a little space. In relation to the length of a top-hat rail, more terminals can be mounted. Since feed-through terminals are mounted directly next to each other on the DIN rail, there is no danger of touching the contacts on the open sides. Without a side cover, a terminal is narrower. A cover is only attached to the last terminal in a row.Which installation aids and which accessories are available for feed-through terminal blocks?For the construction of a control cabinet, you receive numerous well thought-out components that simplify your work. For feed-through terminals, for example, the cross-bridges and busbars already mentioned are available. In addition, you will receive separator plates and end plates, covers, feeds or end blocks as well as test plugs, fuses, labeling fields and other components.  Catalogue content:In this eibabo® catalogue Terminal blocks > Feed-through terminal block you will find items from the following product groups:Item overview:Base clampBolt clampChangeover relayCompartment clampConnecting combsConnection moduleConnection technologyDistribution blockFeed terminalFour-level clampLightning arrowMarshalling boxMini clampMotor connection terminalMotor output terminalMulti-level clampMulti-wire terminalNeutral terminalPotential clampRelay terminalSocketSpring clampsSpring clipSwitching relayTerminal block connectorThermal voltage terminal blockThrough terminalUniversal clampfrom the following manufacturers:Manufacturer overview catalogue Through terminal:ABBEatonEberleHagerMetzPhoenixSchneider ElectricSiemensSpelsbergTE ConnectivityWAGOWeidmüllerWielandWöhner
Multi-level installation terminal - Which multilevel installation terminals are there and what functions do they have in the control cabinet? Are multi-level installation terminals the same as feed-through terminals? What's the difference? How is the assembly done? Here you will find answers to many questions. In the eibabo® technology store you can get multi-level installation terminals from all well-known manufacturers such as ABB, Hager, Phoenix, Siemens, WAGO, Weidmüller and Wieland at top conditions and in large quantities. Delivery is worldwide, fast and safe.Installation multi-level terminals are among the most important components within a control cabinet and fulfill several functions. The terminals represent connecting elements between the incoming cables and lines of an installation and the actual control cabinet installation. The assembly is carried out on the DIN rail.What are installation multi-level terminals?Installation multi-level terminals are multi-pole terminal blocks. The term 'terminal block' not only includes multi-level installation terminals, but also, for example, feed-through terminals, fuse terminals and relay terminals. Surely you have already heard or read about single-level clamps and triple-level clamps. These are other common names for feed-through terminals and tier terminals. When it comes to spring-loaded terminals, push-in terminals or screw terminals, the focus is on the type of wire attachment. But these terminals can also be counted among the multi-level installation terminals. The main feature of the installation multi-level terminals is the potential entries arranged one above the other.What is the difference to a feed-through terminal?The differences between feed-through terminals and multi-level terminals are small and mainly lie in the number and arrangement of the potential entries. A simple feed-through terminal usually only has one potential, while tier terminals can have several potentials. This saves space compared to feed-through terminals, since the feed-through terminals are arranged next to each other as individual terminals. A clear assignment of the different cores is guaranteed by the colored conductor entry openings in multi-level terminal blocks. Tier terminals are therefore more complex feed-through terminals and are often equipped with special functions for building installation, for example with N disconnect terminals, equipotential bonding terminals or distribution feed terminals.How important are multi-level installation terminals for control cabinet construction?With multi-level installation terminals, you achieve enormous flexibility in control cabinet construction. Rigid incoming cables and lines are clearly laid out on the terminals. You thus create flexible connection points to connect the actuators, fuses or other devices in the control cabinet with individual wires. This keeps the entire installation flexible, as there are nodes for testing and changing the entire system. A direct connection without installation multi-level terminals would not be clear and would lead to considerable effort in the event of changes.Image: WAGO 2003-7641 Multi-level installation terminalWith the implementation of a well-structured circuit diagram, each link created in this way takes on a comprehensible function. The installation of the system remains clear. Additions, repairs and maintenance in the future are made easier. Changes to the system are always possible by reconnecting individual wires. The rigid supply lines remain untouched.For a better overviewYou can attach labeling fields to some tier terminals. We recommend using this. Label all devices and connections sensibly. Matching labeling fields are available here in the shop.But this structure offers other advantages. During maintenance work, the electrician can carry out his insulation measurements and other control work directly on the tier terminals. This saves time and money when troubleshooting. For example, many DIN rail mounted devices (REG) only have two contact points for connecting the cables. With the use of installation clamps, you can expand this if necessary. An example: You want to protect several lines with one fuse. Unfortunately, you can only connect the wires from one line directly to the fuse. What can you do? In order to link further lines, establish clear jumper connections on the installation multi-level terminals.How can the cables be attached to the installation multi-level clamps?Each manufacturer builds the multi-level installation terminal blocks slightly differently. However, the principle is the same. While single-level terminals connect only one line as simple feed-through terminals, the installation of several incoming and outgoing lines is possible in multi-level terminals / tier terminals. A three-tier terminal block is designed for the connection of the protective conductor, the N line and the L line. The arrangement in tiers saves a lot of space in the control cabinet. Multi-level terminal blocks are used very frequently, especially in the smaller switch cabinets in private households and in smart home installations. TIP:If a terminal block does not have a connection point for the outgoing protective conductor, snapping it onto the DIN rail ensures 100 percent contact with the protective conductor contact foot. The types of attachment for the cables represent a special distinguishing feature. There are screw terminals, spring-loaded terminals and push-in terminals.With the screw terminal, a screw fixes the respective wire. This method is comparatively time-consuming, especially when dealing with a large system with many connections. Fastening with a screw must be done carefully so as not to damage the solid or flexible cable too much.With the spring-loaded terminal, the electrical contact is made with a mechanical metal spring. The spring is in the form of a curved flat contact with a hole. The wire must be put through the hole to connect. This is only possible if the spring is stretched with a pointed tool. The line will bind as soon as the tool is removed and the spring relaxes. The connection is released in the same way.The push-in connection is a variant of the spring-loaded terminal. Here, too, a spring-loaded metal contact presses against the wire. Installation is tool-free. The wire is inserted into the spring shaft of the multi-level terminal block and the contact is locked directly by the spring force. You need a tool to loosen the connection. Using a small screwdriver, bend the spring contact to the side and the wire will come loose. These connections save a lot of time with cables with solid conductors. Wires with flexible strands can also be fixed using this method, but they should be stabilized with a ferrule.The attachment of the cores using insulation displacement terminals is rare and is only used if your cable is particularly thin. With this method, the conductive contact is made by cutting the wire insulation.Special features of the neutral conductor contactIn addition to models with screw attachment and spring clamps, there are multi-level terminals where you can use an N busbar. With these terminals, the neutral conductor contact is designed in such a way that a busbar can be connected with a flick of the wrist. In this case you need an additional terminal for feeding. To ensure that the rail is held securely, use suitable trestles at the beginning and end of the row. Some clamps also offer mounting levers. Please also fix longer rails every 20 centimetres.Are there different tier terminals for the different cable cross-sections?Cables and lines with different cross-sections are used in electrical installations. This affects the tier terminals. Appropriate terminals are available for all common cable cross-sections. The suitability for certain cross-sections is indicated on the terminals. In addition, there is the option of bridging the N lines and the L lines via several tier terminals, sometimes on several levels. Suitable cable bridges are available here in the shop.Why are multi-level installation terminals open on one side?As you may know, the space available in the control cabinet is specified in modular widths (TE). The specification of the pitch units provides information about the capacity of a control cabinet and helps with the purchase decision. Installation multi-level terminals do not correspond to this grid dimension, but are manufactured as narrow as possible. So the narrower the individual terminal is, the more terminals you can install on a certain area of the DIN rail. Good to know:A pitch unit is 18 millimeters according to DIN 43880:1988-12. The installation width of the devices is 17.5 millimeters (deviation plus 0.5 millimeters) and its multiples. Installation multi-level terminals are typically mounted directly next to each other on the mounting rail. There is therefore no risk of touching the contacts on the open sides. This saves material in production and some space. Without a side cover, a terminal is slightly narrower. Only the last terminal in a row is covered.What are N disconnect terminals?Electrical systems must be checked regularly. The insulation measurement (e.g. between neutral conductor and protective conductor) is an essential part of such a test. As a result, possible insulation faults, which can cause fires and the associated damage to persons or property, are detected at an early stage. To do this, the neutral wire of each circuit must be disconnected. The use of neutral conductor disconnect terminals is therefore necessary in this country in public facilities, workplaces in trade and industry and in fire-endangered premises.  Catalogue content:In this eibabo® catalogue Terminal blocks > Multi level installation terminal block you will find items from the following product groups:Item overview:Cage clampDouble clampFeed blockFeed-through terminal blockFuse plugGround terminalInsta clampInstallation clampMulti-level clampPhase terminal blockSingle clampSpring clampSpring clipSpring terminalTerminal blockThree-wire terminalTier clampTripod clampUniversal clampfrom the following manufacturers:Manufacturer overview catalogue Multi-level installation terminal:ABBHagerPhoenixSiemensWAGOWeidmüllerWieland
Dimming actuator - The technical requirements for the use of dimming actuators are very extensive. Why do I need a dimming actuator and which dimming actuator is the right one for me? In this eibabo catalog you will find many dimming actuators from different manufacturers, for example from the top brands ABB, Berker, Busch-Jaeger, Eaton, EVN, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben various automation systems or conventional applications.How do I plan the lighting correctly?You should not start with the control technology first, because this follows at the very end of the lighting planning. First you should plan the lighting according to necessity, appearance, ambience and your own wishes, followed by the functional requirements and then find the right lights.Save by planning!The more precise, the cheaper the execution of the installations. The more complex the functional requirements are, the more important it is to plan and research a suitable SmartHome system.Only then is the functional implementation carried out, which consists of many other topics.What should I know beforehand?Which lights do I want to install?Do I want to use a conventional installation or a bus system?Should the SmartHome be wired or radio (KNX, DALI, or Zigbee radio protocols such as Hue)?Which lights are switched and/or dimmed together and how?Should it be controlled via app or voice assistant?and much more... ... this results in the following findings, for example:Which cables and lines are required?Which control components (e.g. dimming actuators) have to be considered?To what extent do the operating resources have to be secured?How much space must be provided in the electrical distribution?Do I have to consider special flush-mounted sockets for lights?and much more... What do I have to consider before buying a dimming actuator?Before you buy a KNX dimming actuator, the load types of the equipment and their performance should be checked carefully. There are basically 3 types of KNX dimming actuators. There are dimming actuators with the control type leading edge, trailing edge or universal dimming actuators that recognize the connected load type and automatically activate the correct type of control. TIP:Install a few more lights in the room and use a dimming actuator to create a pleasant lighting ambience. KNX dimming actuators are available for installation in the electrical distribution system, then they have the suffix 'REG' for modular installation devices or as a concealed version 'UP' for installation in a mounting box or junction box or as an installation version 'EB' for integration in ducts or similar. 230V halogen lamps or incandescent lamps, for example, can be operated with both types of control.What is the difference between leading edge dimming and trailing edge dimming?Very simply explained; 12V low-voltage lighting (NV) with a conventional iron-core transformer requires phase control dimming, although these transformers are hardly ever used. 12V low-voltage lighting (NV) with an electronic transformer requires trailing edge dimming.The type of dimming of the dimming actuator can be recognized by the abbreviation 'RL' for trailing edge dimming for incandescent lamps, 230 volt halogen lamps and the abbreviation 'RC' for trailing edge dimming for incandescent lamps, 230V high-voltage halogen lamps, 12V low-voltage halogen lamps, dimmable LEDs and dimmable ones energy-saving lamps. It is also possible that both abbreviations 'RC' and 'RL' can be found printed on the dimming actuator. Often you will also find this imprint: 'R, L, C'. It designates which equipment the dimming actuator can work with (dimmer, transformer, LED). If you find all 3 letters or the abbreviations 'RL' and 'RC', then it is usually a universal dimming actuator.Image: KNX LED universal dimming actuator - Jung 390041SRIn this case, however, the limit values of the power ranges for each type of dimming with connected equipment must be observed. Dimming actuators often have minimum loads, which may not be suitable for the use of LEDs. Trailing edge dimming 'RC' (trailing edge control) is the most common application. Basically, the lamp and the dimmer must be marked as 'dimmable' and fit together. TIP:For LEDs, we always recommend LED dimmers or LED controllers, which have also been developed for exactly this application. If in doubt, you can also contact the manufacturer of the dimming actuator directly if you send a data sheet for the equipment (lamps and, if applicable, ballasts).Can I dim a fluorescent lamp? Are energy-saving lamps dimmable?Yes, fluorescent lamps and energy-saving lamps can also be dimmed, provided the lamp is suitable and marked as 'dimmable' or, in the case of fluorescent lamps, there is a dimmable electronic ballast (EVG) for 1-10V or the DALI standard. You can find KNX dimming actuators for electronic ballasts with a 1-10V interface under Smart Home > Light control unit. Another standard for electronic ballasts is DALI (Digital Addressable Lighting Interface). The advantage over the 1-10V variant is that addressing is possible and there is no wiring according to groups. Further advantages are direct addressing, status messages, scene memory and a wide range of dimming options with the DALI ECG.How do I find out if my lamp / luminaire is dimmable?Basically, the light source used should first be checked to see whether it is dimmable. You can find this marking in the item description or on the packaging. Lamps that have already been planned and fitted with light sources must be checked for dimmability and the type of control with the control gear used.How do I determine the power for my dimming actuator?It must be clear which light groups are to be switched and dimmed together and how high the total output (W/VA) of the group is in order to select the appropriate KNX dimming actuator with regard to the required maximum output, the minimum load and the number of channels as well as the type of control Find. eibabo always recommends a thorough analysis of the application prior to purchase. Lamps and illuminants must be technically analyzed and checked against the technical data of the dimming actuator. In addition, there are countless different parameter properties of KNX dimming actuators between the manufacturers.Why can't I dim my LED light?All dimming actuators meet the standard requirements for dimming. In addition, many manufacturers offer additional interesting parameters. These parameters may be functionally important for your project. The marking KNX universal dimming actuator does not automatically mean that these dimming actuators are also suitable for dimming the LEDs you use.  Catalogue content:In this eibabo® catalogue Installation bus systems > Dimming actuator for bus system you will find items from the following product groups:Item overview:ActuatorBasic moduleBinary inputBrightness controlBus technologyControl blockControl unitDimmer plugDimming actuatorsDimming extensionDIN railEnergy efficientExpansion moduleFan driveFunction moduleLight controllerLightbulbsLightingLighting technologyLuminaire controlOutput moduleRadio controlRadio receiverRetrofit lampsSocket coverStarter packUniversal dimmerUniversal dimming actuatorfrom the following manufacturers:Manufacturer overview catalogue Dimming actuator:ABBBerkerBusch JaegerEatonElsoEltakoESYLUXFinderfrogblue AGGiraHagerIssendorffJungLegrand BticinoLegrand SEKOLingg & JankeMDTMean WellMertenPehaSchneider ElectricSiemensThebenWielandZumtobel
Distributor-timer - digital - Don't you also think that many electrical consumers don't have to be in operation all day? Would you like to save costs and conserve resources? This is possible with timers for the control cabinet. Find out here which functions digital distribution time switches can take on and which special features you should pay attention to when buying.At eibabo® you will find the right digital distributor time switch for installation in the electrical distribution board. We carry a large selection of Astro timers, weekly timers and yearly timers. Manufacturers of high-quality devices include Hager, Finder, ABL Sursum, Theben, ABB, Stotz S&J, Legrand (BT), Grässlin, Eltako and Schneider Electric. In the following text we will go into the individual variants in more detail.What are distribution timers?A time switch for the junction box is an electronic or mechanical device that switches electrical consumers on a time-controlled basis. These can be switched on and off without having to flip the switch yourself. This can be useful in private households as well as in commercial companies and in the industrial sector. The purposes of the distributor time switches include, among other things, the automatic switching on and off of lighting systems or the control of fixed house installations such as heating, ventilation, lawn sprinklers and air conditioning units. This not only saves you time, but also money.NoticeDistribution time switches are often offered in grid dimensions (pitch units). Depending on the equipment, such a device requires one to four modular widths in the control cabinet.The advantages of a timer are therefore obvious: electricity costs can be reduced effectively through the targeted control of your electrical devices. At the same time, you have the option of making your home less attractive to burglars, for example by simulating your presence using optionally available random functions.You can also get digital or analogue timers for the socket in another catalog from the eibabo® shop. Their function is comparable to that of the distributor time switches. However, the area of application extends to 'mobile' devices that are not permanently installed. These include Christmas lights, aquarium technology or decorative items such as fountains.What functions do distribution timers offer?A high-quality distributor time switch offers numerous functions and programs for the individual setting of the switching cycles. These include:60 min program / 24 h programWeekly program / annual programAutomatic summer/winter time changeoverholiday programimpulse programcycle programastro programrandom programPermanent switching ON/OFFexpiration timerhour meter Image: Theben TR 644 top2 RC distribution time switchWhat is the difference between each type of timer?We often come across terms such as astro timers, weekly timers or yearly timers. With regard to a purchase decision, the question then arises as to whether there are significant differences between these models. The basic function is the same for all models. The differences lie in the detail and the setting options of the individual variants. The astro function of a timer adjusts the switching times daily to the seasonally changing length of the day. In other words: When the days get longer in spring, the device switches on a little later every evening and a little earlier every morning. This process is calculated electronically and does not require a brightness sensor, for example, which would otherwise have to give the command to switch the light on or off. With a weekly timer, you can set individual switching times for each day of the week. In contrast, the function of a very simple time switch is limited to setting switching cycles within 24 hours.Already knew?Modern timers have a powerful power reserve. In the event of a power failure, this ensures the function of the timer for up to 10 more years.The annual time switch offers even more extensive functions. This means that different switching times can be provided for each calendar day and vacations and public holidays can be taken into account.Do distribution timers require a separate power supply?Digital timers always require energy to operate. As a rule, a distribution time switch is clamped onto the DIN rail of the control cabinet and supplied with mains voltage via an integrated power pack. Time switches that are exclusively battery operated are rare. These are typically analogue variants, which are used, for example, as 'door openers' in stables when there is no electricity.Is a digital timer always better than an analogue model?An analog timer works mechanically, a digital timer works electronically. Whether one or the other variant is more suitable for you depends on your requirements for the device. Mechanical timers usually have a higher-level switch with which you can switch the device off completely, switch it on permanently or switch it to switching mode. Switch buttons arranged in a circle represent the daily routine. There are usually 48 buttons and each button stands for half an hour. Activate or deactivate the corresponding switching period by pressing or pulling out. Compared to analog timers, digital timers offer significantly more setting options and functions. In contrast to mechanical timers, you can usually set several switching programs down to the minute over days or weeks. The distribution timer is operated using buttons and a display. TIP:If you want to control more than one device with the distribution timer, choose a model with the appropriate number of channels. This saves a lot of space in the control cabinet. Times and switching programs are clearly shown on the display. In terms of accuracy and functionality, a digital time switch is clearly superior to the analogue version. However, it requires a certain learning phase to understand the technology and set switching programs. If you only need 'rough' and daily recurring switching processes, analogue time switches are still a good alternative. These are set up and ready to use in just a few seconds.Can distributor time switches be programmed using an app or externally?There are distributor time switches that have Bluetooth and can be configured using an app. This allows you to display and change the switching states via smartphone or tablet computer. The prerequisite is the coupling between the input devices and timers within a network. Another way of programming the switching times is to use manufacturer-specific software. You can transfer the switching information to a special memory card via the USB interface of your computer. The memory card can then be connected to the time switch on the construction site/in the switch cabinet and the switching data can be loaded into the switch and vice versa.Doesn't a distribution timer consume more electricity than it saves?If the focus is on switching a consumer (e.g. the lighting) on and off, a distribution time switch is of course useful. As a rule, active end devices consume significantly more power than a timer. The question asked above relates to switching off a device that would otherwise run in standby mode for hours.To answer this question, a distinction must be made between an analogue and a digital time switch. An analogue model is less complex and usually has an output of less than 1 watt. With an electricity price of 40 cents per kilowatt hour, for example, the consumption costs are around 1 cent per day with 24 hours. With a digital timer, you have to assume around 2 watts and thus calculate electricity costs of 2 cents per day. In this calculation example, the investment costs for one or more time switches should also be taken into account.You can now compare this with the standby power consumption of your devices. This essentially depends on the type, age and number of devices. Old devices with displays consume more power in standby than modern electronics with only one control LED. A mix of new and old devices in the household currently results in an average consumption of 1 to 2 watts per device. If you need a separate timer for each electrical device, using them to save standby power is therefore not economical. The situation is somewhat different with distribution time switches, which can switch several devices or machines with a high standby current at the same time. This may save you on standby electricity costs, although this is not the primary reason for using a timer in these cases either. TIP:Pay attention to the shortest switching time of the device if you want to switch short intervals. Some devices only switch every minute and only a few devices switch every second or even faster. An example: If you have a terrarium with a sprinkler system, the nozzles should usually only spray for a few seconds. This is to maintain high humidity. Prolonged spraying may flood facility and animals.  Catalogue content:In this eibabo® catalogue Devices for distribution board- / surface mounting > Digital time switch for distribution board you will find items from the following product groups:Item overview:Astro timerBuilt-in timerDaily timerDigital timerDistribution timerEnergy efficientExpansion moduleInstallation timerJunction boxLighting controlLocation dependentPosition dataPower reserveProgram clockQuartz timerSeries installationTimerTimer moduleTimersUniversal timerWeekly programWeekly timerYear time switchfrom the following manufacturers:Manufacturer overview catalogue Distributor-timer - digital:ABBDoepkeEatonEltakoFinderHagerHamaLegrand BticinoSchneider ElectricSiemensTheben
Installation contactor mdrc - Do you want to know why an installation contactor hums? Find out here. Or would you like to activate and stop large consumers using a remote switch? Then you need a high-quality and inexpensive installation contactor from the eibabo® technology store. With us you will find a large selection of high-quality installation contactors from many well-known brands. We carry installation contactors (REG) and accessories from the following manufacturers: Schneider Electric, Eberle Controls, Siemens, Eltako, ABB Stotz S&J,Finder, Eaton (Moeller) and Legrand (BT).All offered installation contactors are characterized by:excellent processing qualitylittle to no hum during operationquiet switching operationsvery good industrial qualityhigh switching capacitylong lifetime What is an installation contactor in electrical engineering?An installation contactor is an electrical device that is primarily used to protect electrical systems and devices from overload and short circuits. Installation contactors are mainly used in building installation for automation. In many cases, this involves the automatic switching on and off of electrical devices and systems. The installation contactor assumes the task of a remote switch, which switches a larger current with a lower current. In the area of electrical distribution installation and control panel installation, installation contactors are used, among other things, as series installation devices (REG) for mounting on DIN rails or support rails (35 mm) according to DIN EN 50022.What are the typical areas of application of an installation contactor?An installation contactor can be used, for example, to switch heating systems on and off automatically to protect them from overheating. Other automation processes include switching and controlling three-phase motors, lighting systems, ventilation, pumps, cable pulls, gates, shading systems and other building automation drives.How does an installation contactor work?Installation contactors usually work with operating voltages of 230V or 440V and with actuating voltages of 230V or 24V. There are also versions where both voltages are 230V. In addition to the housing, an installation contactor consists of an excitation coil, coil core, metal armature, switching contacts and armature return spring. There can be multiple of these essential functional elements in the installation contactor. The device consists of a control circuit and a load circuit. If current flows through the control circuit, the load circuit closes and also carries current. In the idle state (OFF), the switching contacts do not touch. TIP:If a contactor hums, this is not yet a cause for concern. This is due to dust and dirt or the rivets in the coil core loosening over time. Incipient wear on the short-circuit ring can also be a reason. The task of the excitation coil is to generate a strong magnetic field when current flows. The coil core serves as a carrier for the coil and strengthens its magnetic field. This is the only way to overcome the force of the return spring. The magnetic effect becomes large enough to move the armature. As soon as the armature is attracted, the switch contacts touch and the contactor is active (ON). The return spring returns the armature to its original position when the coil's magnetic field disappears. The contacts loosen and the device goes back to sleep mode. This means that the device only stops by itself in the OFF position. The control circuit of the coil and the load circuit of the switch contacts are isolated from each other. The armature creates the connection between the circuits and enables the consumers to be switched on the load circuit. A contactor is therefore an electromechanical switch designed for high power, which is similar to a relay in terms of its function.Can several contactors be combined?You can combine multiple contactors to meet specific installation and automation needs. You have even more diverse control options if you use contactor relays to control the installation contactor or to display an operating status. Contactors of various combinations with a maximum of four contacts are often used (e.g. two NO contacts / two NC contacts or three NO contacts / one NC contact).Contacts in an installation contactorAn installation contactor is usually provided with different types of contacts. A distinction is made between main contacts and auxiliary contacts.Good to knowThe contacts of a contactor are divided into working contact (closer), break contact (opener) and changeover contact (changeover contact). The changeover contact is a combination of opener and closer. Opener and closer can also be combined in one installation contactor.The main contacts described in the function are used for the power to be switched. This makes it possible to connect large consumers. The auxiliary contacts are designed as signaling lines for contactor control and signal display.What is an auxiliary contactor?You have a wide range of control options when using contactor relays. Power contactors have a significantly higher switching capacity than contactor relays and switch load circuits of large consumers. Auxiliary contactors switch control voltages for small loads and are designed for small consumers and displays. You can use it to implement logical operations and control power contactors.Image: Schneider Electric A9C20844 installation contactorWhat is the difference between a contactor and a relay?Relays serve primarily as circuit breakers and control switches in devices and are important components in many control processes. There are different types of relays that perform different functions. The most common types include protection relays, monitoring relays, auxiliary relays and reclosing relays. Relays open and close circuits or contacts by responding to electrical quantities such as current or voltage. A contactor is an electromechanically controlled circuit switch. Here a circuit with a low power level is switching a circuit with a higher power level. A contactor is designed for operation with normally open contacts. If there is no power on the device, there is no switching connection. Relays can usually open and close. Another difference lies in the performance of the respective device. Contactors are used in control circuits with higher electrical voltages and higher currents. This results in further safety-relevant differences. Contactors work with tie rods and return springs, relays with hinged armatures or rotary armatures. Sparking caused by the separation of live contacts is reduced in the contactor with arc suppression. As a rule, relays switch much faster than contactors, are lighter, smaller and consume less energy. Due to the more complex structure, contactors are more expensive than relays.  Catalogue content:In this eibabo® catalogue Devices for distribution board- / surface mounting > Installation contactor for distribution board you will find items from the following product groups:Item overview:AC contactorBuilt-in contactorBuilt-in distributor deviceChangeover contactorContactor moduleControl contactorDC contactorHeater contactorHigh power contactorInstallation contactorInstallation contactorsInstallation relayLighting contactorLoad contactorMagnetic switchModular installation devicePower contactorSeries built-in contactorSmall contactorUniversal voltage contactorfrom the following manufacturers:Manufacturer overview catalogue Installation contactor mdrc:ABBDoepkeEatonEberleEltakoFinderHagerLegrand BticinoSchneider ElectricSiemens
Electricity meters - Have you always wanted to know how much energy individual devices in your household consume? This catalog from the eibabo® shop offers you the right measuring instruments for this. Here you can get high-quality electricity meters and many other meters at top conditions. In our modern home we use numerous electrical devices. In addition to lamps, washing machines and refrigerators, media technology is a major energy consumer. Televisions, computers, chargers for smartphones and building automation are powered by electrical energy. Although some of these devices also help save electricity, it is interesting to know how much energy they actually use.What are electricity meters?Electricity meters are devices for displaying electricity consumption or energy consumption in electrical systems. AC induction meters are predominantly used in households, which directly display the consumed kilowatt hours. To find out how high your energy consumption is in a certain period of time, you need to take two measurements. Subtract the value of the second measurement from the value of the first measurement.Image: ABB B23 113-100 three-phase meter M-BusWhat types of electricity meters are there?There are two main types of electricity meters. These are used by the utility companies. On the one hand there are the electromechanical meters and on the other hand the so-called intelligent meters or smart meters. If you operate a solar system and feed electricity into the grid, you need a third type of meter, the bidirectional meter. These measure the current drawn and the current fed in. As a rule, you have little influence on the electricity meters that come from your energy supplier. These are installed where the power lines enter your building. This catalog is about electricity meters, which you can also install. This allows the consumption of a specific section of your installation or the consumption of an individual end device to be measured.How is an electromechanical meter constructed?Electromechanical induction meters are widely used and can be found in many homes. These contain an electrically conductive, non-magnetic, rotatable 'Ferraris disc'. The disk is driven by the interaction of magnetic fields generated by two electromagnets.Magnet 1 is powered by the current from the incoming power linesMagnet 2 is powered by the current demanded by the building's electrical circuits The rotation of the disk is slowed down by two permanent magnets, which exert a proportional opposing force. The aluminum disc drives a scrolling mechanism that displays kilowatt hours or fractions thereof.How does a smart meter work?Electronic electricity meters have been on the market for several years. The current standard for electronic electricity meters are digital electricity meters and so-called smart meters. These work in a similar way to electromechanical electricity meters. Instead of mechanical moving parts, they contain a battery and a communication chip. The chip sends meter readings wirelessly to a collection point. This happens several times a day depending on the time of day. The data is usually transmitted to the electricity supplier every quarter of an hour via power lines, mobile communications or high-frequency networks. Already knew?The chip is also known as an encoder or ERT device. This uses the same frequency as many cordless phones. However, the device is designed to avoid interference. The battery in the communication chip in digital electricity meters is designed for a service life of 15 to 20 years.What are the advantages of measuring with an electronic electricity meter?With an electronic electricity meter, you can not only determine how much energy you use, but also when. At first glance, this may be less important additional information. But knowing exactly when and how much electricity you are using can save you a lot of money. Electricity prices vary throughout the day. When demand is high, electricity costs more than when demand is low. Constantly rising energy costs are leading to deregulation of the electricity markets. In the future, utilities could offer electricity tariffs that bill for the electricity provided based on the time of use. This would be a significantly fairer billing method than the current variant, which is based on average costs.smart gridSmart grids are intelligent power networks that take generation, storage and consumption into account. This allows fluctuations in power in the network to be compensated. Networking and coordination is carried out using modern technologies and decentralized energy management systems.Smart meters can also be read remotely. Utility companies thus save operating costs and working time. Electronic electricity meters are therefore an essential part of the so-called smart grid. The devices help you to question your habits and save money if you use your electricity off-peak. Think of buying an electronic electricity meter as an investment in your future.How do I find the right electricity meter?Modern electricity meters can be used to display electricity consumption in real time. Especially in the KNX area, intelligent electricity meters offer many advantages. These support you with load management within your installation and with the monitoring of services and end devices. This saves you money and time because you can make adjustments according to your consumption profile. The use of data loggers or programmable logic controllers makes it easier to display, control, analyze and monitor the data. You can integrate models with a KNX interface directly into your building automation system using Engineering Tool Software (ETS). But which things are still important when buying?number of phasesWhen choosing an electricity meter, please consider how many phases are required. The most common models are single-phase or three-phase. If your current system that you are getting your data from is single phase, you will need a single phase electricity meter. If the electrical system is three-phase, use a three-phase electricity meter. As a rule, the devices can be mounted on a DIN rail. The measurement is carried out flexibly for various performance parameters such as:True RMS Voltage (Vrms)True RMS Current (Irms)Active power (kW)Active energy (kWh)Apparent Power (kVA)Apparent energy (kVAh)Reactive Power (kVAR)Reactive energy (kVARh)Power Factor (PF)frequency The devices can be used both on the primary side of the low voltage and on the secondary side of the medium voltage and high voltage.The ampPay attention to how many amps you need for the system. Commonly, smart electricity meters support 60 amps, 100 amps, and 200 amps. The right choice depends on your power system. Using a 100A electricity meter for a system that requires 200A would be impractical.Bus systems and networksIntelligent electricity meters communicate via various media and protocols. Please determine in advance which communication protocols will be used. Well-known fieldbus systems are AS-Interface, CAN, CANopen, M-Bus, EtherCAT and others.  Catalogue content:In this eibabo® catalogue Meters > Kilowatt-hour meter you will find items from the following product groups:Item overview:Active consumption meterActive power meterAdditional roomBidirectional counterCable conversion converterCombination counterCombination meterConverter meterCurrent measuring adapterDIN railDIN rail counterDirect meterElectricity meterEnergy cost meterEnergy managementEnergy meterHeat pump systemsMeasuring accessoriesMeasuring technologyPower factorPower meter plugSingle phase meterSpare PartsTariff meterThree-phase meterTransducerTwo-tariff meterTwo-wire meterfrom the following manufacturers:Manufacturer overview catalogue Electricity meters:ABBABNBachmannBergEatonEltakoEMU-ELEKTRONIKFinderFroniusGMC-I MesstechnikHagerHamaJanitzaLingg & JankeNZRSchneider ElectricSiemensStiebel Eltron
Frequency converter = - Do you have an AC motor and want to control its speed? Then the use of a frequency converter is an interesting product for you. A frequency converter is always used when you need permanent speed control on a machine. This can be, for example, pumps or compressors, but also fans, mixers or mills with electric motors. A frequency converter converts the fixed mains voltage into a variable voltage. This enables not only operation of the motor at a constant speed, but also acceleration and deceleration. In this way, the speed of a machine can be adapted to the current work requirements, energy can be saved if necessary, or production processes can be varied over time.Use the high-quality frequency converters from the eibabo® shop, protect materials with speed control and thereby extend the service life of your machines. Manufacturers of high quality goods are ABB, Eaton, KEB Automation, Maico, Mitsubishi, Omron, Rockwell, Schneider Electric and Siemens.What is electrical frequency?In order to explain electrical frequency and to be able to deduce the function of a frequency converter, we must first look at the basics of electricity generation. There is direct current and alternating current. Direct current always flows in one direction. Alternating current periodically changes direction. This change is represented in a diagram in the form of a sine wave, which is alternately in the positive and negative area of the zero point. Accordingly, an alternating voltage is also an oscillating electrical voltage.Already knew?The Danish company Danfoss was the first company to start series production of frequency converters. This was in 1968.The AC frequency describes the number of cycles in this sine wave per second and corresponds to the number of changes in direction. This is given in Hertz (Hz). 1 Hertz corresponds to a complete cycle from the zero point to the positive range, to the negative range and back to the zero point. The more cycles per second occur, the higher the frequency. The usual mains electricity in Germany and Europe has a fixed frequency of 50 Hertz.How does a frequency converter cause a change in motor speed?The standard speed of an AC motor is tuned to a specific frequency. This is based on the structure of the respective motor. A constant magnetic field with stationary poles prevails between two field magnets. Within this magnetic field is a rotating, also magnetic 'anchor' with two poles. If alternating current is passed through the armature, its polarization changes in time with the alternating current. With a mains frequency of 50 Hz, this happens 50 times per second. Accordingly, the attractive and repulsive forces between the field magnet and the armature change direction 50 times. Once set in motion, this alternation ensures a certain rotational movement of the armature and speed of the motor. Each change in frequency therefore also causes a proportional change in motor speed. The frequency converter is responsible for changing the frequency.The advantages are:infinitely variable control of the desired nominal speedReach very high and very low speedsdirect switching of the direction of rotation Picture: Schneider Electric ATV320U22N4C frequency converterWhat are the reasons for a change in engine speed?An almost constant frequency is applied to the classic AC network and therefore only one speed is available to you. The frequency converter regulates the frequency and voltage of the power supplied to the motor. That is why this device is often also called a speed controller. There are many reasons why the engine speed needs to be adjusted:to save energy and increase efficiencyto optimize the flow of manufacturing processesto protect material and extend the service life of machinesto meet the requirements of processing various materialsto adjust the torque / power of a driveto lower the noise levelto reduce peak loads Modern frequency converters have network and diagnostic functions. This makes it possible to integrate the devices into the control system of a plant and to monitor and optimize all processes.Where are frequency converters used?Frequency converters are used in numerous industries and applications. These devices are mainly found in compressor, pump and fan drives. But the speed of conveyor belts, production lines or cranes can also be controlled with frequency converters. An adapted or infinitely variable speed enables energy-efficient and optimized production processes.What should be considered when buying a frequency converter?The correct selection of the frequency converter is crucial for the optimal operation of the corresponding devices. Before selecting the drive, determine the number of input phases. Will the device be three phase or single phase? Will the device handle resistive loads, inductive loads, capacitive loads, or mixed loads? The individual loads cause different inrush currents when starting. Please consider this. Before you buy, find out about:the requirements of the operating environmentthe starting torquethe load torque characteristicsthe speed control range and the static speed accuracy  TIP:You are very flexible with regard to the location. Frequency converters are available for installation in the control cabinet, for wall mounting and for decentralized field use. Since a certain level of expertise is required to evaluate these properties, we recommend consulting an experienced electrician.  Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Frequency converter =< 1 kV you will find items from the following product groups:Item overview:Built-in converterConverter unitDrive amplifierEngine controlEngine outputFan controlFan speed controllerFrequency controllerFrequency converterMotor controllerPump converterServo amplifierServo converterServo driveSpeed controllerSpeed settingVariable speed starterfrom the following manufacturers:Manufacturer overview catalogue Frequency converter =
