Eltako pulse switch with potential-free contacts, also suitable for central control. Standby loss is only 0.03 to 0.4 watts. Priorities for central control can be selected. The latest hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. With additional control inputs for central on and central off for 8 to 230V AC, galvanically isolated from the local control input. Supply voltage matches the local control voltage. Very low switching noise. Glow lamp current from 110V control voltage up to 50mA in switch positions 1 to 3 and 5 to 7. By using a bistable relay, there is no coil loss power and no heating even when switched on. After installation, wait for the automatic short synchronization before connecting the switched load to the network. Maximum current is the sum over.
