Cutt-off relay blind shutter - Separating relays are electrical components used in the installation of blinds and roller shutters. Especially when several drives are connected in parallel, isolating relays ensure that they really work separately from each other, even if they are controlled centrally. If this were not the case, the different drives could influence each other, for example due to different switching times, which could ultimately lead to incorrect functioning and, in the worst case, to damage to the components. With high-quality isolating relays from the eibabo technology store, you can ensure that your blinds and roller shutters function correctly. You can get high-quality control and isolating relays from well-known manufacturers such as Busch-Jaeger, Gira or Siemens for your installation here at your eibabo specialist center for technical building automation.Catalogue content:In this eibabo® catalogue Domestic switching devices > Isolator relay venetian blind you will find items from the following product groups:Item overview:Awning control relayBlind controlBlind control relayControl relayControl unitCoupling relayCut-off relayEngine control unitEngine controlsEngine group relayIsolator relay venetian blindModular installation deviceMultiple control relayMultiple controllerObject controlParallelingRelay switchSeparating relay blindShutter controlShutter motorShutter relayShutter switchSwitch rangefrom the following manufacturers:Manufacturer overview catalogue Cutt-off relay blind shutter:BerkerBusch JaegerElsoEltakoGiraHagerIssendorffJungKaiser NienhausMertenPehaPROTEC.classRademacherSchalkSiemensSomfyWarema
Voltage monitoring device - For safe voltage monitoring, eibabo offers a wide range of voltage monitoring devices, voltage monitoring relays and voltage measuring relays, mains voltage monitoring devices, and power supply monitoring relays and grid disconnection relays. Devices to monitor the voltage are usually used for monitoring undervoltage. Many devices are suitable for undervoltage monitoring in three-phase systems (each phase against the neutral wire) with a fixed threshold value. Sometimes the voltage monitoring devices are equipped with a fixed hysteresis as well as an integrated test button. When you press the test button on the device, the output relay drops. The devices can also be used for monitoring a single phase: Connect all unused inputs with a connected phase, because the missing voltage would otherwise be displayed. The output relay of the voltage monitoring device switches on when the measured voltage of all connected phases exceeds the fixed value (including hysteresis). The output relay switches off again when the voltage of one of the connected phases falls below the fixed value. Please remember that no error message occurs in devices for sole undervoltage monitoring if there is reverse voltage from a consumer that is higher than the set threshold value. Mains decoupling relays monitor voltage and frequency in three-phase systems and can, in connection with inverters with integrated isolated network detection, be used for monitoring the NA-protection. Many voltage monitoring devices monitor the presence of the neutral conductor, the current under-voltage and over-voltage. The respective threshold usually has its own adjustable delay. If a voltage fault occurs, the corresponding relay (undervoltage output and overvoltage output) opens after the delay set by you. If the neutral conductor fails, the two relays normally open immediately without delay. We provide high-quality devices for voltage monitoring from all major manufacturers such as Schalk, Finder, Metz Connect, Ziehl, Dold & Söhne and Siemens, Bender, Hager or by Schneider Electric or Tele Haase.Catalogue content:In this eibabo® catalogue Relays > Voltage monitoring relay you will find items from the following product groups:Item overview:Alarm relayError memoryGrid monitoring relayMains protectionMeasuring relayMonitoring deviceMonitoring relayNetwork guardNeutral conductor monitoringOvervoltage relayPhase failure relayRelayRelay for measuring and reporting v. undervoltagesRotary field monitoringRotating field directionSurge monitorThree-phase monitoring relayUndervoltage monitoringUndervoltage monitoring deviceUndervoltage relayVoltage limit switchVoltage measuring relayVoltage monitorVoltage monitoringVoltage monitoring deviceVoltage monitoring relayVoltage relayWindow voltage relayfrom the following manufacturers:Manufacturer overview catalogue Voltage monitoring device:ABBABNBenderDoldEberleFinderHagerMetzPhoenixPilzSchalkSchneider ElectricSiemensTeleWielandZiehl
Time relays - What are time relays used for? Sometimes it may be that your structural conditions make it necessary to delay electrical switching processes. Perhaps you still have to walk through a dark garage after activating the light switch, or a motion detector should only be activated after you have left a room. In these and many other scenarios, the use of a time relay can be useful. This ensures that a certain function is only activated or deactivated after a certain period of time. You can set the length of this period of time on the relay.What is a time relay?Timing relays or delay relays are simple control relays that control defined events based on time sequences. The difference between a classic relay and a timer relay is when their output contacts open and close. In a control relay, this occurs when voltage is applied and removed from the coil. With the time relay, the contacts can open or close before or after a certain delay. The installation usually takes place in the control cabinet on the DIN rail. TIPThe set time intervals can be set between milliseconds and hours depending on the relay. Typically, the delay is initiated or triggered by one of two methods:applying or switching off a control voltagethe occurrence of an impulse / trigger signal What functions do time relays perform?It is often difficult for the layperson to understand technical descriptions. When describing the functions of timing relays, we encounter terms such as control voltage, response delay, release delay, pulse shaping or make contact. In order to give you an understanding of how the time relays work, we describe the switching options below using simple examples.To make our examples easier to understand: Always assume that you only switch a 'control voltage' on or off using a switch or button in order to set a switching process (scenario) in motion. However, the actual circuit goes via the relay. Pressing a switch or button when using a switching relay does not necessarily lead to an immediately visible action. You only tell the relay that the preset scenario should now run and that it has to carry out the corresponding switching at the desired time. The following ten scenarios are most commonly implemented with time relays:Scenario 1 - The fallback delayThe release delay is also called switch-off delay.Example: When the control voltage is switched on using the switch (ON), the relay closes the circuit and the light lights up. If you press the switch again (OFF), the light stays on and the set delay time starts to run on the timer relay. The relay keeps the current flowing. At the end of the time period, the relay breaks the circuit, turns off the light and goes into sleep mode. When the light is switched on again using the switch (ON), the process starts again.Scenario 2 - The response delayThe response delay is also called switch-on delay.Example: When the light is switched on using a switch (ON), the time set on the relay starts to run immediately. Only after the time has elapsed does this close the circuit and the light lights up. Now when you press the switch again (OFF), the relay will directly break the circuit, turn off the light and go into sleep mode. When the light is switched on again using the switch (ON), this process starts again. Depending on the model, after the response delay has been interrupted, the time that has already elapsed remains stored or is deleted.Scenario 3 - The impulse controlled response delayThe switch-on delay is not triggered by a permanently applied control voltage, but by a pulse (briefly applied control voltage). These are also referred to as trigger signals.Example: In contrast to scenario 2, a short impulse in the control voltage is sufficient to set the scenario in motion. You don't turn on a switch, but press a button, for example. A preset time starts to run at the relay and then it closes the circuit for a previously defined period of time. Then it goes back to sleep mode. You can usually set both time periods individually. A classic application is a door opener. To do this, briefly press a button. After the set time (this can only be milliseconds), the relay interrupts the circuit on the electromagnet of the door lock for e.g. 3 seconds. During this time, the door is open and visitors can enter. After these 3 seconds have elapsed, the relay automatically restores the power supply to the electromagnet and the door is locked again.Scenario 4 - response delay and release delayThe circuits from scenarios 1 and 2 are combined with each other.Example: When the light is switched on using a switch (ON), a set time immediately begins to run on the relay. Only after this period of time has elapsed does this close the circuit and the light begins to shine. If the switch is then actuated again (OFF) and the control voltage is thus interrupted, a set delay time begins to run. The relay keeps the current flowing. Only after the time has elapsed does the relay interrupt the circuit, switch off the light and go into idle mode. Depending on the model, after the response delay has been interrupted, the time that has already elapsed remains stored or is deleted. Depending on the relay, the response delay and release delay are either of the same length or can be set independently of one another.Scenario 5 - The relay as a clock (starting with a pulse)You know this from the turn signal in the car. It is a flasher relay.Example: You press the switch (ON) and the relay closes the circuit immediately. The light glows. After a defined period of time, the relay interrupts the circuit and the light goes out. After another defined period of time, the relay closes the circuit again and the light shines again. This interval continues as long as the control voltage is present. Press the switch (OFF), interrupt the control voltage. The interval switching ends at the relay and it goes into the idle state.Image: Finder 83.02.0.240.0000 time relayScenario 6 - The relay as a clock (starting with a pause)This scenario is similar to scenario 5, it just starts with a pause, not an impulse.Example: You press the switch (ON) and the preset pause time starts to run on the relay. Only then does the relay close the circuit. The light glows. After a defined period of time, the relay interrupts the circuit and the light goes out. The break time begins again. Then the relay closes the circuit again and so on. This interval continues as long as the control voltage is present. Press the switch (OFF), interrupt the control voltage. At the relay, the interval switching ends immediately and it goes into idle mode.Scenario 7 - The fleeting switch-on relayExample: When the control voltage is switched on using a switch (ON), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again. It goes into sleep mode even if control power is still present (switch still ON). This scenario can only be repeated if the switch has been actuated (OFF) after the wiping time has elapsed. If the switch is confirmed (OFF) during the wiping time, the control voltage is interrupted and the relay also interrupts the circuit immediately. The rest of the wipe time is deleted. The process can start over.Scenario 8 - The fleeting switch-off relayExample: When switching off the control voltage using a switch (OFF), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again and goes into the idle state. This scenario can only be repeated if the switch has been actuated (ON) after the wiping time has elapsed. If the switch is confirmed (ON) during the wiping time, control voltage is applied again and the relay interrupts the circuit immediately. The rest of the wipe time is deleted. The process can start over. A classic use case: you leave a building in the dark and switch off the main light. The orientation lights turn on and you have time to leave the building. After that, the orientation light also switches off automatically.Scenario 9 - The fleeting on and fleeting off relayThe circuits from scenarios 7 and 8 are combined with each other.Example: When the control voltage is switched on using a switch (ON), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again. It goes into sleep mode even though control power is still present (switch still ON). When the control voltage is switched off using the switch (OFF), the relay closes the circuit again and the light lights up again for the specified wiping time. When this expires, the relay breaks the circuit, turns off the light and goes into sleep mode.Scenario 10 - The time relay as a pulse shaperThe application of the control voltage (regardless of whether it is long or short) is converted into a switching process of the same length.Example: You press a switch (ON) to start the scenario. The relay closes the circuit for a previously defined period of time. The light glows. After the time has elapsed, the relay opens the circuit again and goes into the idle state. The light goes out. It is irrelevant whether you press the switch again while the light is on (OFF) or whether you do this much later, when the light has already gone out. The process only starts again when control voltage is applied again (switch ON).This is how you saveMany of the scenarios described can be implemented with multifunction time relays. So you are always flexible and only have to invest in one device.In addition, it is also possible to combine several time relays with one another in order to create corresponding dependencies. Please refer to the product descriptions to find out whether additional functions such as a two-stage response delay or switch-off pre-warning can be implemented with a relay.Here in the eibabo® technology store you will find many inexpensive products for the field of control technology and automation technology.
