EltaKo pulse group switch for central control, 1 + 1 non-potential-free contacts 10A/250V AC, for a 230V AC motor. Standby loss is only 0.4 watts. Designed for installation. Dimensions: 45 mm long, 45 mm wide, 32 mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. This pulse group switch executes commands from sensor relays or from switches and buttons, controlling a 230V motor for a shading element or roller shutter. Control, supply, and switching voltage is 230V. A1, A7, and A8 must be controlled with the same potential as L. By using bistable relays, there is no coil loss and no heating even in the switched-on state. After installation, wait for the automatic short synchronization before connecting the switched load to the network. The control input A1 is operated with a universal button.
