Timer - A conventional time switch usually switches an electrical relay contact at set times. This is used to realize specific control and automation functions. However, in this eibabo catalog you will find special timers for various automation bus systems, such as radio bus or KNX bus system. KNX time switches, generally, do not dispose of direct switching contacts, but provide the status in digital form as telegrams on the respective bus system or by radio. Depending on the manufacturer, the KNX time switches have diversified but also different characteristics. Most KNX switches feature a day program, week program and year program. Some KNX timers offer a connection option for a DCF or GPS antenna. An automatic summer / winter changeover as well as astro programs. A definition of the geographical location of the building extends the range of options. Switching functions with output of dimming values, switching ON / OFF or UP / DOWN for blinds or shutters, heating control for comfort / standby or night mode, scene release as well as master / slave function are other possible options of KNX time switches. Updating the date and time at KNX displays or other KNX devices in the system by sending the information to the bus are further advantages. Some manufacturers also offer holiday databases, countdown timers and operating hour counters, as well as random programs for simple presence simulations in case of absence to deter potential burglars. A standby in case of power failure is also often standard. What is different is the way to get started. Some manufacturers offer the possibility of direct commissioning of times at the display, programming keys or a separate add-on software or programming solely via the ETS. One should also consider whether another KNX device, which already contains timer programs, is planned in the system, for example KNX weather stations with astro function and GPS / DCF, KNX visualizations (KNX server) KNX displays or complex KNX control and display panels. eibabo provides KNX time switches, KNX time transmitters, wireless timers, KNX year timers, KNX radio switches, KNX week timers, KNX radio blind switches, KNX synchronization timers, digital time switches as well as KNX UP timers of all leading manufacturers, such as ABB, Berker, Busch-Jaeger, Eltako, Hager, Issendorf, Jung,Legrand, MDT, Merten, Peha, Siemens, Theben or Warema.Catalogue content:In this eibabo® catalogue Installation bus systems > Time switch for bus system you will find items from the following product groups:Item overview:Application moduleAstro timerBus systemBus system timerColor displayDistribution timerEIBEnergy efficientLight controlLighting controlMounting rail timerNikobusProgram clockProject clockRadio timerTime switchTime switch for bus systemTimerTimer clockTimer moduleTimersWeek clockWeekly timerYear time switchYear timerfrom the following manufacturers:Manufacturer overview catalogue Timer:ABBBerkerBusch JaegerEltakoHagerMDTMertenSomfyTheben

Light control unit - In this eibabo category you will find light control units of various automation systems (radio, LCN, KNX). The most common light control units in this catalog are for the KNX bus system. The light control units in KNX are usually dimming actuators for electronic ballasts that means for connecting devices with 1-10 V interface to the KNX bus system. Some explanation: A ballast unit is required for operating a gas discharge lamp, such as a fluorescent lamp (fluorescent tube). Electronic ballasts (ECG) operate at a high frequency ( eibabo catalogue Smart Home Interface-media gateway in eibabo catalog Smart Home. The advantage compared with the 1-10 V type is that addressing is possible and wiring by groups is not necessary. Further advantages are a direct response, status messages, scene memory and a variety of dimming options with DALI ballast.

Motion detector - complete - What are the special features of a motion detector? What are the main differences between motion detectors and presence detectors? Before you decide on a device, weigh up which one is the right one for your application. In the following, we will describe the properties and provide you with information on how to make a purchase decision. In our range you will find a large selection of complete motion detectors from all major manufacturers.What is a motion detector?The motion detector is an electronic sensor that detects movements in its immediate vicinity. Motion detectors, guards and presence detectors work as electrical switches. These are used to switch on lighting or to trigger another switching action. Active motion detectors usually work with electromagnetic waves (high frequency or Doppler radar) or with ultrasound. Passive motion detectors work based on the infrared radiation in the area. Detectors with PIR sensors react to temperature changes caused by people walking by.Image: Busch Jaeger 6845/11 AMG-204 outdoor motion detectorWhat questions should you ask yourself before buying a motion detector?Before you buy one of the high-quality and inexpensive devices from the eibabo® shop, you should limit the large selection based on your intended use.Should the device be installed inside or outside?Do you prefer a built-in device / flush-mounted device or should the motion detector be mounted on the wall or ceiling?What should the motion detector react to?Are large, small, bright or dark areas being monitored?Should the motion detector trigger certain actions?Is there a suitable power supply?Do lines and cables have to be relaid?Should the device be protected from unauthorized access or vandalism? What is the difference between presence detectors and motion detectors?Basically, a distinction is made between conventional presence detectors / motion detectors and devices for building automation. Presence detectors can usually also be used as motion detectors. The differences and significant advantages of a presence detector compared to a motion detector lie in the more variable usability. While motion detectors carry out a simple light measurement, presence detectors constantly measure daylight and/or mixed light with a special sensor. This has a spectral sensitivity similar to that of the human eye. In contrast to motion detectors, disturbances caused by artificial light are avoided.Already knew?A motion detector is used to switch on when motion is detected. The purpose of a presence detector is to switch loads on or off in order to save energy. It switches when no more movement is detected or a brightness limit is exceeded.Briefly explained using the example of an automatic door: If there is sufficient brightness during the day, the lighting should not be activated while the door should open when a presence is detected. Both should be switched on when it is dark. You can usually implement this function via several channels in the presence detector. Use the motion detection channel to switch the lighting depending on the brightness. You can use the presence detection channel to switch other consumers, in this case the door opener, regardless of the brightness.Which areas of application are typical for presence detectors and motion detectors?Presence detectors offer a complex sensor system. This captures sensitive movements. Typical areas of application are office workplaces and other workplaces. A motion detector is preferably used in small rooms, garages, carports, corridors, cellars, stairwells or for monitoring outdoor areas.Can presence detectors and motion detectors be used for building automation?Conventional versions are primarily intended for the areas of application described above. If you want to integrate such a device into your smart home, you usually need a separate interface to the KNX bus. The more elegant solution is to use detectors that are already KNX-capable. KNX presence detectors and KNX motion detectors have a wide range of control parameters indoors and outdoors. With this you can:Switch or dim lightsblinds or roller shuttersControl heating, air conditioning and ventilationSet up master/slave functionsBuild blocking operation functions and logic functionsImplement features for pets (animal swath).and much more Multiple channels are often provided to control individual functions.Are there any recommendations for installing motion detectors and presence detectors?The detection areas and necessary mounting heights differ depending on the model. Choose equipment that suits your needs. Pay attention to the performance of the sensors and the angle of coverage. Basically, the following applies: the detection area increases with increasing installation height. However, the sensitivity decreases. Motion detectors and presence detectors detect a specific area of the environment. This can be a 360° detection or the targeted monitoring of a specific area.From own experienceWe recommend not choosing a detection area that is too large. Use additional detectors to ensure uninterrupted surveillance. The investment in additional technology is low compared to a system that works poorly or not at all.Pay attention to the necessary degrees of protection if a detector is exposed to moisture, the weather or mechanical influences. Clean the sensor regularly. By avoiding sources of interference, you ensure proper function and eliminate false signals. Sources of interference include:Objects that obstruct the viewdazzling light sourcesObjects that rapidly change the temperature of the detection area Why is my motion detector or presence detector not working properly?Proper functioning depends on various factors. Was the installation carried out correctly? Is the device suitable for the intended purpose? The malfunction often lies in a detection range that is not optimally set. Control the direction, angle of view and distance to the target area. TIP:The fewer movements you expect in the monitored area, the longer you should choose the follow-up time. The run-on time is restarted again and again as long as a detector detects a change.Who makes high-quality presence detectors and motion detectors?Here in the shop you can get detectors from the brands ABB, Berker, Busch-Jaeger, eQ-3, Esylux, Gira, Hager, Jung, MDT, Merten, Peha, Siemens, Steinel and Theben at top conditions.

Socket board - How many consumers can be connected to a socket strip? How do you integrate the power strips into office furniture? You can find out in this eibabo® catalogue, and find the right product for you from the large selection of socket strips. Socket strips are also referred to as multiple sockets or power strips. These provide a connection to the power grid for several electrical consumers with a standardized plug connection. In contrast, an extension cord usually only has a single connection.Which criteria are important for the purchase of a power strip?A power strip is a relatively simple tool for expanding the electrical installation. Nevertheless, it is advisable to pay attention to a few basic things. These are:Sufficient number of slotsStable material quality of cable, plug and socketsThe presence of surge protectionSpecification of a test mark such as the GS seal or the VDE sealAn adequate IP rating for the intended useAdditional equipment (switches, child protection and so on) How many devices can be connected to a power strip?In principle, the number plays a subordinate role. It depends on the sum of the power. Please note that under no circumstances should too many powerful consumers be connected to a socket strip. Remember that a device doesn't have to be big to require large amounts of power. You should therefore not connect high-power devices such as refrigerators, washing machines, dryers, space heaters, air conditioners or ovens to a power strip. Small consumers such as lamps, computers, entertainment devices or printers do not pose a problem. TIP:The connected loads should not exceed a combined output of around 2300W at 10A or 3600W at 16A measured at 230V mains voltage. Please make sure that you do not connect multiple socket strips in a row. Otherwise the resistance (impedance) could become too large due to the concatenation.Can socket strips also be sources of danger?As long as you are using a power strip properly, there is nothing to worry about. Pay attention to the performance of the connected devices and to a safe laying of the cable. Never lay a line under a carpet that many people walk over every day. Over time, this can cause the wires in the line to break, heat up, and cause sparks. Check the cable and the power plug of the strip regularly. If you find any damage, replace the power strip.Image: Bachmann 333.400 19 inch power stripWhat types and equipment are possible with socket strips?Combinations of different equipment features are also often available. At eibabo® you can get socket strips with switches and overvoltage protection or master/slave socket strips with switches, among other things. Further explanations would be, for example:Switch, toggle switch or foot switchtimersOvervoltage protectionchild lockMaster/slave power strips Or the following statements:19 inch power stripsALU socket stripsOutdoor sockets and garden sockets or combination plugsDesk boxes and table socketsEnergy cube (SCHUKO or up to 400V CEE)Multiple crafting barsSocket strips for IEC cold devicessocket towerssurge outlets What are the advantages of power strips with surge protection?Power strips with overvoltage protection protect connected devices from damage because voltage peaks are reduced. An upstream coarse protection in the meter cabinet and medium protection in the electrical distribution is also advisable. TIP:We recommend the use of surge protection if you supply valuable technology with the additional sockets. A surge protector has another protective element that absorbs additional current. These can be current fluctuations or voltage peaks, which could otherwise damage or destroy your connected electronics.What are master/slave power strips?Power can be saved with master/slave socket strips. An integrated electronic circuit detects whether power is flowing through the master socket. If power is present at the master socket, the slave sockets are activated. If no more current flows through the master socket, the slave sockets switch off. The typical application is a computer and its connected peripheral devices. If the computer is switched on via the master socket, monitors, scanners and printers also start. Turning off the computer also disables all other devices, avoiding going into sleep mode.What do I use 19 inch power strips for?19 inches is a standard installation size for server cabinets. If you want to install many devices in your server cabinet, you need an adequate power supply. With a 19-inch socket strip, up to 10 devices can be connected. The socket strip is adapted to the profile rail of the 19-inch server cabinet and can be mounted directly.We recommendIn order to set up additional protection, we also recommend an uninterruptible power supply (UPS) in addition to integrated overvoltage protection.You can also get high-quality UPS systems in the eibabo® shop. Use our intelligent search.What options do I have for permanent installation of power strips?You need electricity at practically every workplace. With socket strips for mounting on, under or in a desk, you can create connection points for monitors, printers, beamers and telephones. So you don't have to crawl under the desk every time you want to connect something. In addition, the connections don't get dusty as quickly because they are easy to access for cleaning or are integrated into a housing. In addition to the desired number of power connections, other interfaces (USB, HDMI and others) are often available. In addition to mounting on or under the tabletop, it is sometimes possible to retrofit it by drilling or cutting out the tabletop.With socket units you remain flexible. These are housings that you can individually equip with suitable inserts. This is how you put together the perfect supply bar yourself.

Air conditioner switch cabinet - Is it very warm in your control cabinet? Are you concerned that the high temperatures could damage your technology? Read here what options you have for cooling your control cabinet and which criteria you use to select an air conditioning unit for the control cabinet.If many devices are installed in a control cabinet, they usually also generate heat. This leads to increased temperatures, which could damage the components. In the private sphere, this does not happen very often. Within commercial and industrial control cabinets, however, the number of devices is usually significantly higher and air conditioning is necessary. Control cabinet air conditioning systems are therefore mainly used for cooling communication devices, transformers and switchboards.Image: Rittal SK 3361.500 wall-mounted cooling unitUnder what circumstances are air conditioning units used for the control cabinet?When the air temperature outside the cabinet is too high or the air quality is poor, simply using ventilation to dissipate the heat may no longer be sufficient. Control cabinet air conditioning systems are designed in such a way that they dissipate excess heat from control cabinets and device housings to the atmosphere. This serves to protect the heat-sensitive components from overheating, because the service life of electronic components is reduced at higher operating temperatures. The air conditioning of control cabinets extends the service life of electrical components and ensures increased fault tolerance of the devices. Use a control cabinet air conditioning system if:the temperature inside the housing must be equal to or lower than the ambient temperaturethe required heat dissipation cannot be provided by the environmentthe ambient air is very pollutedthe ambient air contains too much humidity The typical areas of application are server farms, telecommunications systems, automation systems and control cabinets, transformer stations and substations, radio stations, data storage stations and energy storage systems.How does a control cabinet air conditioning system work?The design of industrial air conditioning systems provides for two completely separate air circuits, which prevent the air in the cabinet from mixing with the ambient air. This means that the cooling system maintains a suitable temperature inside the case without the ingress of dirt, dust, moisture, water or corrosive fumes. TIP:Make sure that the housing or the control cabinet is also sealed airtight. If necessary, add the necessary seals to the door or close ventilation outlets. Most of the air conditioning units for control cabinets available from eibabo® work according to the principle of the air-air heat exchanger. These typically use copper tubing with small fins to ensure optimal heat exchange between the two air circuits. The copper tubes are filled with coolant, which easily changes its state of aggregation between liquid and gaseous. In order to cool the switch cabinet, the warm air from the switch cabinet is routed through the ribs of the pipe system. The copper tubes and fins absorb the heat, heating the liquid in the copper tubes while cooling the air. A heat exchange takes place. The heated liquid in the copper tubes turns into a gas and moves to the other side of the unit to the external air circuit. This causes the cooling of the copper pipes and the coolant according to the opposite principle. The heat absorbed in this way is released into the atmosphere. The coolant becomes liquid again and flows back to again absorb heat in the control cabinet. A cycle is created. Unlike other cabinet cooling systems, air-to-air heat exchangers have no moving parts. There are low maintenance costs, the devices work efficiently and economically.Far less common are the thermoelectric cabinet coolers. These work according to the Peltier effect and are therefore also called Peltier coolers. These represent special types of cooling systems, which are used particularly in harsh and dangerous environments.Jean PeltierIn 1834, the French physicist discovered that the flow of current at the junctions between two dissimilar electrical conductors causes a temperature difference.The functional principle of thermoelectric cabinet coolers is based on the fact that heat is either absorbed or given off when a voltage is applied to the connection point between two materials. Semiconductors are typically used here, the different number of free electrons of which ensure the required energy difference. When current flows, heat is transferred from one terminal to the other and a cooling effect occurs.What does master/slave function mean?An appropriate temperature in the control cabinet ensures the function of the devices installed in it. It is therefore often necessary to avoid an increase in temperature even if a device fails or the performance of a device is no longer sufficient. Although the performance of one device is typically sufficient, a second air conditioning device serves to secure the first system and is connected to it. Both devices exchange data, measured values and error messages. Master and slave work to support each other, alternately or as a substitute. The master device thus takes care of the primary cooling, while the slave remains in stand-by mode and switches on automatically when required.How and where can the air conditioning for control cabinets be installed?Systems are offered for a wide variety of purposes. You get devices for outdoor use, devices protected against vandalism and devices for indoor installation. It is mounted on the roof or on the side walls of the cabinet. With roof-mounted air conditioners, the heated air escapes to the rear, left, right or even upwards. This means that it can be used in a row or set up close to the wall without any problems. In the case of air conditioners for wall mounting, installation, partial installation and attachment are possible, depending on the space required.What should I look out for when buying a switch cabinet air conditioning unit?If the ambient temperature is higher than the required temperature in the cabinet, you should consider using a cabinet air conditioner. The following points, among others, should be considered when making the selection:Type of installation of the control cabinet according to VDE 0660 Part 500Ambient conditions (temperature, dirt and humidity)maximum desired control cabinet interior temperaturePower loss of the electronic components in the control cabinetIP degrees of protection If you install an air conditioner for the control cabinet, please pay attention to the following things:The control cabinet must be sealed.When mounting on the cabinet roof, this should be reinforced if necessary.The condensate drain must be introduced into the outlet opening so that no condensate flows into the cabinet. Some models do not have a drain. Instead, the condensate evaporates.A door switch should be installed to turn off the air conditioner while the door is open.Keep the air circulation in the cabinet clear and avoid obstacles at the air inlet and air outlet. At eibabo® you only get high-quality, reliable and powerful air conditioning units from well-known manufacturers such as Kraemer & Kraus, Rittal, Schneider Electric and Siemens.
