Stand-by loss only 0.05-0.4 Watt. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 module = 18mm wide, 58mm deep. This impulse-group switch processes the commands from sensor relays or switches and pushbuttons and, depending on the setting of the rotary switches on the front, switches a motor, motor isolation relay MTR12-UC UC or DC motor relay DCM12-UC. Supply and switching voltage 12..230V UC at terminals +B1\/-A2. The control voltage at terminals A3 to A8 must have the same potential. The operating principle of this impulse-group switch is that, on the one hand, \"up, stop, down, stop\" is controlled by impulses (contact 1 closed – both contacts open – contact 2 closed – both contacts open), and on the other hand, up or down can be specifically selected via additional control inputs. \"Dynamic\" refers to control inputs where an impulse of at least 20ms is sufficient to close a contact. \"Static\" is a control input where the contact is only closed for as long as the control command is present. The terms \"up\" and \"down\" apply to roller shutters, blinds, and awnings. For awnings, \"up\" means retracting, and \"down\" means extending. For windows, \"up\" means opening and \"down\" means closing. Function rotary switch: AUTO 1 = In this position of the lower rotary switch, the local comfort slat reversal function for blinds is activated. With local control using a pushbutton on A3+A4 (connect with a jumper) or a double pushbutton on A5\/A6, a double impulse causes slow rotation in the opposite direction, which is stopped by another impulse. AUTO 2 = In this position of the lower rotary switch, the local comfort slat reversal function for blinds is completely deactivated. AUTO 3 = In this position of the lower rotary switch, the local comfort slat reversal function for blinds is also deactivated. However, the dynamic central control inputs A5 and A6, which are dynamic in AUTO 1 and AUTO 2, are initially static, allowing the reversal of blinds by pressing a button. They only switch to dynamic after 1 second of continuous activation. Arrow up\/arrow down = Manual control is performed in the arrow up (up) and arrow down (down) positions of the lower rotary switch. It has priority over all other control commands. WA = The automatic slat reversal for blinds and awnings is set with the middle rotary switch. 0 = deactivated, otherwise activated between 0.1 and 5 seconds with the set reversal time. In this case, only when going down, after the delay time set with the upper rotary switch has elapsed, is a change of direction carried out, e.g., to tension awnings or to set blinds to a specific position. RV = The delay time (RV fallback delay) is set with the upper rotary switch. If the impulse-group switch is in the \"up\" or \"down\" position, the set delay time runs, at the end of which the device automatically switches to \"stop.\" The delay time must therefore be chosen to be at least as long as the shading element or roller shutter needs to move from one end position to the other. Below this rotary switch is the LED indicator for the delay times WA and RV. Local control with pushbutton at terminals A3+A4 (connect with a jumper). With each impulse, the impulse-group switch changes the switching position in the sequence up, stop, down, stop. Local control with roller shutter toggle switch at terminals A3 and A4. Local control with roller shutter double pushbutton at terminals A5 and A6. A push impulse activates the \"up\" or \"down\" switching position. Another impulse from either of the two pushbuttons immediately interrupts the process. Dynamic central control without priority at terminals A5 (up) and A6 (down). A control signal activates the \"up\" or \"down\" switching position. Another control signal (\u0026lt;700ms) at this control input immediately interrupts the process; another control signal (\u0026gt;700ms) continues the ongoing action. Without priority because the local control input A3+A4 (with jumper) and the central control inputs A7 and A8 can immediately override, even if the control contact at A5 or A6 is still closed. Dynamic central control with priority at terminals A7 (up) and A8 (down). With priority because these control inputs cannot be overridden by other control inputs as long as the central control contact is closed. Otherwise, the function is like dynamic central control without priority. These central control inputs A7 and A8 are used by the sensor relays MSR12 and LRW12D for rain, frost, and wind functions, as these must have absolute priority over other sensor commands.","brand":"ELTAKO","offers":[{"title":"Default Title","offer_id":56295503790411,"sku":"ELT21200401","price":68.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/5075\/6427\/files\/5ce00b8440ffd9b2e49fe375b8465d64.webp?v=1768552637","url":"https:\/\/solarvic.at\/en\/products\/eltako-stromstoss-gruppenschalter-uc-1-1-schlie-sser-nicht-potenzialfrei-16a-250v-ac-21200401-verkaufseinheit-1-stuck","provider":"SOLARVIC | Photovoltaik \u0026 Haustechnik","version":"1.0","type":"link"}
