Blind actuator - How can I automate my shutters and blinds? Can the time of day, the weather and the position of the sun be taken into account? We provide recommendations and information on the purchase of KNX blind actuators and show you what options the technology offers you in everyday life.If you want to build a new house or renovate an existing building, many questions arise. The technical equipment in particular must be well thought out, because a later change is then only possible with a lot of effort. If you already include the advantages of intelligent building automation in your planning, then the opening, closing and shading of the windows will also play an important role.Useful application examples for controlling blinds or roller shutters:the up and down of roller shutters and blinds according to time specificationsturning the slats of blinds based on the brightness in the roomthe automatic opening of roller shutters or blinds when windows are openedthe simultaneous operation of several shading systemsthe flexible control or regulation of the roller shutters when you are absent via a smartphone appthe automatic drive to the safety position in the event of a storm alarm and back after the all-clearthe blocking of operation for certain peopleautomatic shading according to geographic location and position of the sun (astro control) The use of modern KNX blind actuators supports you in realizing all these projects. They ensure more security, greater comfort and increase the value of your property. What distinguishes a KNX blind actuator from a KNX switching actuator?All motorized equipment such as blinds or roller shutters can be automated using KNX blind actuators. Standard 230V blind actuators therefore have 2 channels per switching output. A channel to drive up and a channel to drive down. The channels are mutually locked to prevent damage to the drive. So only one phase can be switched through to the drive at a time, never both at the same time. TIP:Never use KNX switching actuators to control blinds and shutters without a downstream isolating relay. With classic KNX switching actuators, the channels are not mutually locked. It would therefore be possible to connect more than one phase to the drive. This can quickly lead to damage to the technology. There are models which, depending on the configuration, can be used both as a switching actuator and as a shutter actuator. Please read the specification of the respective actuator.What should be considered during installation?Motorized 3-point drives must not be connected in parallel. Group formations may only be carried out using isolating relays or group control devices if the manufacturer does not provide for any isolating function. For example, for 4 windows, each with a drive, you should use a KNX blind actuator with 4 channels. There is also the option of operating several drives via one channel using conventional isolating relays. The shutter actuator channel then controls the isolating relay and the drives are connected to the isolating relay. In the meantime, however, the prices for the KNX actuators have fallen massively, so that there is hardly any need to reduce costs by using isolating relays. TIP:When selecting your components, always prefer one blind actuator channel per blind motor. For example, if you would like to integrate 6, 8 or 12 blinds into your system, you will find the appropriate actuator here in the shop.Are blind actuators with 230V AC better than models with 24V DC?This question is not about better or worse. Rather, the type of voltage of the drives should always be considered. The drives of blinds or roller shutters are often designed as 230V AC (alternating voltage) or 24V DC (direct current). That's why you have to buy the matching blind actuator or roller shutter actuator. A 24V DC blind actuator or roller shutter actuator has a plus and a minus connection. A suitable KNX actuator generates the direction of travel (up/down) by changing the poles (pole reversal).Do shutter actuators require a separate power supply?The 24V DC mains supply is not provided by the actuator and must also be installed externally depending on the power requirement for simultaneity (central commands). In this case, very large power supply units can become necessary, which, in addition to high costs, also require a large amount of space. If you can, order 230V AC drives and matching 230V KNX blind actuators from the supplier. These also require their own power supply, but no additional power supply units.That is the reasonSo-called monostable relays are installed in the shutter actuators, which are open and not active when idle. However, the relays continuously require energy as long as they are closed (e.g. for the duration of a blind movement). The bus voltage alone cannot cover this requirement.In contrast, there are bistable relays in classic switching actuators. These only require some energy in the brief moment of switching from one position to another. This can be implemented via the bus and an additional power supply is usually not necessary.What do I need an SMI KNX blind actuator for?SMI stands for 'Standard Motor Interface' and is an intelligent, uniform and manufacturer-independent interface in building automation. This is used to connect various operating resources, such as window drives, roller shutter drives or blind drives to a higher-level building management system. There are SMI KNX blind actuators for drives with an SMI interface. These intelligent drives are therefore able to exchange data telegrams across manufacturers.Which actuators are recommended for controlling roller shutters and blinds?eibabo® carries KNX blind actuators, KNX roller shutter actuators and KNX SMI actuators from ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens, Somfy, Theben, Warema and many other manufacturers.Over 25 years of experienceAll actuators that you get here in the shop are of high quality and reliable. We regularly use these actuators in our projects all over the world.Benefit from our low prices and take advantage of safe, fast and worldwide shipping.1-byte communication object - what is that?In any case, make sure that your blind actuator or roller shutter actuator has a 1-byte communication object for the runtime and slat, in order to be able to enable automatic or targeted control if required.There are no slats in roller shutters, which is why roller shutter actuators do not have the slat communication object, only Up/Down/Stop. Roller shutter actuators often have a 1-bit object for a defined positioning movement that can be set via the ETS software.1 byte means that values between 0-255 can be approached, which correspond to 0-100% related to the travel time. The parameters often allow the running time to be set according to the driving time. The travel time of the blind or roller shutter is entered once in the actuator using the ETS software, namely for a complete opening or closing for each channel of the actuator. There are also actuators for evaluating limit switches, which the motorized drive provides.Image: KNX blind actuator ? Eibmarkt JA.6.230The extensive application of the KNX blind actuator / roller shutter actuator JA.6.230 from Eibmarkt® shown here enables a wide range of parameterization via the communication object, including scenes for runtime and slats, blocking functions, automatic functions, security functions and alarm functions, movement limitations, position feedback and much more.Can a layperson use the ETS software to program the KNX devices?Don't be put off by the term 'programming'. The ETS software is only used to assign and parameterize certain actions. Programming skills or learning a programming language are not required. If you have some imagination to understand logical connections, then you are quite capable of creating a project.our recommendationFor more complex projects, a certain amount of experience is of course helpful. Have the basic project created by a qualified system integrator. In this way, you will later be able to easily change important parameters yourself if circumstances require it.Roughly explained: Imagine the folder system on your Windows PC or iOS computer. Here you create your own structure, save files in it and create links to other folders. This is similar with the ETS software. The 'folders' can be floors or rooms and the 'files' in them are the sensors or actuators of the respective room or electrical distribution cabinet, which you then link to one another.What types of installation are there for KNX blind actuators?KNX blind actuators are available for every type of installation at eibabo®. For example, for installation in the electrical distribution, then these carry the suffix 'REG' for series installation devices or as a flush-mounted version 'UP' for installation in a mounting box or junction box or as a built-in version 'EB' for integration in ducts or similar. However, additional protection must also be taken into account for built-in versions depending on the installation.

Impulse switch - Do you want to be able to switch lighting from different places? Or should the light be switched on centrally in different areas of the building? No problem. We will explain to you the possibilities offered by the use of impulse switches. Benefit from our huge range of high-quality impulse switches from well-known manufacturers. Favorable prices, numerous secure payment methods and worldwide shipping make the eibabo® technology store a leading specialist electronics centre. Definition:Impulse switches are electromechanical or electronic devices for the simple and energy-saving control of lighting or other consumers. Impulse switches are also referred to as impulse switches or remote switches.How does a impulse switch work?The impulse switches are switches which are actuated electromagnetically or electronically. These are also known as impulse switches or remote switches. The operating principle is similar to that of a classic ballpoint pen, except that it naturally works without electricity. Impulse switches switch on with an electrical impulse at the control inputs and switch off again with another impulse. The distance to the pulse generator is irrelevant. From a technical point of view, impulse switches are bistable relays or flip-flops, since they have two stable rest positions. Each time the connected button is pressed, the impulse switch receives an electrical impulse. This causes a change in the switching status, which is stored mechanically or electronically until the next pulse. This is the essential difference to a monostable relay. This only switches 'on' as long as a connected button is pressed and then automatically returns to the initial state 'off'.What is the difference between electromechanical impulse switches and electronic impulse switches?Electromechanical impulse switches are comparable in structure and function to an installation contactor. In addition to the housing, this consists of the excitation coil, coil core, metal armature, switch contacts and armature return spring. Flowing current creates a magnetic field in a coil and the metal armature is attracted. The switching contacts close. As soon as the coil no longer generates a magnetic field, the armature is returned to its original position by spring force. Unlike an installation contactor, however, the switching contacts of the electromechanical impulse switch do not open as a result. These remain closed by means of a locking mechanism. Only a further impulse causes the latching mechanism to change and the associated opening of the contacts.Electronic impulse switches switch using transistors, which work as electronic switches and influence each other. A so-called bistable multivibrator is created. The current switching status is always determined by the previous status and is not stored in a locking mechanism but electronically. The switching process is completely noiseless. Since no mechanics are used, the wear and tear of electronic impulse switches is lower.Where are impulse switches installed?Impulse switches are usually offered in two designs. On the one hand as an REG device (= modular installation device) for mounting on a DIN rail in the electrical distribution. On the other hand, the devices are installed in switch boxes or junction boxes. This installation can be flush-mounted or surface-mounted.What are the advantages and disadvantages of impulse switches?In electrical installations and in electrical distribution installation, impulse switches can be used instead of off switches, changeover switches and cross switches. In this way, several switching points can switch the same load. The wiring required for the surge circuit can usually be implemented more easily and often more cost-effectively than with other circuits. You can also use impulse switches with three or four switching states. With such impulse series switches, you can map more complex switching processes in a relatively simple way. A classic application is switching the same load (e.g. a lamp) from several switching points. You know this scenario from:Staircases in the private environment or public buildingslong corridors in company buildingsRooms or halls with multiple entrances in hotels or production facilities In these cases you will usually find buttons on all floors or at all entrances in order to be able to switch the lighting on and off from all locations.Good to knowWhen 'switching', the load current only flows through a potential-free switch contact and not through all buttons. This reduces the susceptibility to failure. If a button fails, the circuit with the remaining buttons will continue to function.In addition, there is the option of centrally controlling several impulse switches. Using an additional module, all connected impulse switches can be reliably switched on or off. This happens regardless of the current switching position of a respective impulse switch. Practical example: An employee in an office building switches off the lighting in a central location at the end of a working day.However, electromechanical impulse switches also have a disadvantage. The devices produce a clicking noise when switching. This can be perceived as annoying. During installation, please ensure good sound insulation of the electrical distribution. Also consider this when mounting in the switch boxes of bedrooms or children's rooms. In these cases, use noiseless electronic impulse switches.Image: Eltako ES12DX-UC impulse switchFor what performance are impulse switches designed?The current impulse switches are designed with switching coils for 12 V AC/DC, 24 V AC/DC or 230 V AC. Impulse switches with monostable switching relays constantly require a small amount of electrical energy, while electronic impulse switches with bistable switching relays work with practically no standby loss.Where can I get high-quality impulse switches at particularly low prices?You can buy impulse switches for electrical distribution installation at low prices from eibabo®.

Soft starters - Would you like to avoid suddenly occurring high starting currents when switching on an electric motor, reduce wear and tear on the motor and thus extend its service life? Find out here how a soft starter works and which criteria you can use to select such a device.What is a soft starter?Soft starters, soft starters or soft starters can basically be used in all electric motors. The devices are used in particular for asynchronous motors that are operated with alternating current. The starters work according to the fact that the torque developed by the electric motor is proportional to the square of the starting current and, correspondingly, proportional to the applied voltage. Thus, with a soft starter, by reducing the voltage at the moment the motor starts, you can adjust the torque and current. So, the task of these devices is to keep the motor parameters (current, voltage, torque and so on) within safe limits during the start. This is done to:to relieve the engine drive train when startingto limit the inrush currentto avoid a voltage drop in the mains voltageprevent the miniature circuit breaker in the circuit from responding too quicklyprevent engine overheatingEliminate dropouts and irregularities in the course of the mechanical driveextend engine life What is an asynchronous motor?To understand the importance of soft starters, we need to know something about the motors they are used in. Electric motors run on either direct current or alternating current. When it comes to AC motors, we mainly differentiate between asynchronous motors and synchronous motors. The difference between the two motor variants lies in the detailed design and the interaction between the rotor and stators in the magnetic field generated.Already knew?In a synchronous motor, the rotor speed is always equal to the rotational frequency of the electromagnetic field. In an asynchronous motor, there is a difference between the rotational speeds of the rotor and the rotating magnetic field in the stator.Asynchronous motors of small and medium power are the most commonly used electric motors and are used both in industry and in household appliances. In the industrial environment, three-phase asynchronous motors are used most frequently, for example as drives in construction, in traffic, in public utilities or as drives for water supply devices. The main problems of these engines are:the high starting current, which can be many times higher than the nominal current and thus leads to problems with the performance stabilitythe inevitable difference between engine torque and load torque. When switching on, the torque is often available in fractions of a second. This sudden force can lead to failure of the drive train. A soft starter avoids these problems by slowing the acceleration and deceleration of the motor. As a result, starting currents can be reduced and irregularities in the mechanical part of the drive as well as hydraulic shocks in lines and valves when starting and stopping the motors can be avoided.What is the starting current?The principle of operation of asynchronous motors is based on electromagnetic induction. The build-up of a back EMF from the application of a changing magnetic field during engine start-up causes transients in the electrical system. Definition transientTransients in electric motors are brief voltage peaks caused by switching on the electrical circuit. These transients can affect power supplies and other connected devices. When starting, the engine accelerates to full speed. Meanwhile, the starting current can reach many times the full load current. During this time, the cables must carry more current than when they are running. The voltage drop in the system is also much greater when starting up. This becomes especially clear when starting a powerful power unit or a large number of engines at once.This is why soft starters are increasingly being used when starting high-performance electric drives. The function of the starters is to supply voltage to the motor windings evenly from zero to nominal, which also allows the motor to accelerate smoothly to maximum speed. During the starting process, the soft starter gradually increases the applied voltage and the electric motor accelerates to the nominal speed without high torque peaks and current surges.How a soft starter worksYou have now learned about the main problems involved in starting induction motors. Soft starters counteract these problems and can be either mechanical or electrical or a combination of both. Mechanical soft starters directly counteract the sudden increase in engine speed by limiting the torque, for example, with brake pads, fluid couplings, magnetic locks or counterweights.The electrically constructed devices gradually increase the current or voltage from an initially low level to a maximum voltage. This starts the motor smoothly and gradually accelerates it to its rated speed. These starters usually work with an amplitude control and can therefore also start up when idling or under load. Devices of the newer generation use phase control methods and also start drives with heavy starting.Image: Siemens 3RW4037-1BB04 soft starterWhat types of soft starters are there?Soft starters are phase controlled. Thus, three types of soft starters are used: devices with one, two and with all controlled phases. The first variant is applied to single-phase motors to provide reliable protection against overload and overheating, as well as to reduce the effects of electromagnetic interference. The devices of the second type usually contain a bypass contactor in addition to the semiconductor control board. After the motor has reached rated speed, the bypass contactor is activated and supplies DC voltage to the motor. The three-phase type is the optimal and most technically advanced solution. It provides reliable current and magnetic field strength limitation without phase distortion.What should you consider when buying a soft starter?The main feature of a soft starter is the current rating. This value should be 'many times' greater than the value of the current flowing through the motor winding. How high this 'multiple' is depends on the severity of the launch. When it comes to motors for fans or pumps, the starting current is about three times higher than the rated current. Certain saws or press machines are often devices with heavy starting. These are drives with a large moment of inertia. Their starting current is about five times higher than the rated current. For motors with particularly difficult starting, the starting current can be eight to ten times higher.Please noteA soft start takes time and excess energy is converted into heat. To repeat the starting process, the starters must cool down. Therefore, if your process requires frequent switching on and off, choose a soft starter for heavy or extra heavy starting (even if your machine doesn't actually need it).Decide on a device that controls the required number of phases. In addition, a soft starter works according to a preset program. In other words: The device increases the voltage to the nominal value within a certain time. An integrated control unit with feedback function allows you to control this process and compare voltage and torque or the differences between rotor and stator.If necessary, pay attention to the ability of the starter to work when accelerating or braking. This would require an additional, integrated auxiliary contactor that bridges the main circuit so that it can cool down. This prevents phase asymmetry and overheating of the motor windings. With some models, you can set certain parameters manually using a rotary potentiometer on the device or digitally using a microcontroller. Consider whether you need additional functionality or features. These include:a certain type of protectionthe presence of power saving modesrestart capabilityWorking at reduced speed TIPA properly selected soft starter can double the service life of electric motors and save up to 30 percent electricity. With a soft starter from the eibabo® online shop, you are opting for high-quality goods from well-known manufacturers such as Eaton, Schneider, ABB or Siemens. If you want to control the speed of a machine not only at the beginning, but permanently, then the use of a frequency converter would be an alternative for you.
