Eltako Impulse switch

2 potential-free switches 16A/250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No standby loss. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Either universal control voltage 12..230V UC at the control input +A1/-A2 or 230V with up to 5mA glow lamp current at the control input (L)/-A2(N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No continuous power supply required, thus no standby loss. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. By using a bistable relay, there is no coil loss and no heating even in the switched-on state. The relay contact can be either open or closed at startup and synchronizes during the first operation. The terminal connection layout is identical to the electromechanical impulse switch S12-200-. Maximum current as a sum over both contacts is 16A at 230V. If this impulse switch is in a circuit monitored by a field disconnector, no additional base load is required, but the monitoring voltage must be set to maximum. The electronics have no independent power supply and therefore consume no power in both contact positions. Only during the short control pulse of just 0.2 seconds does the control current flow, which activates the microcontroller. It reads the last switching state from its non-volatile memory, switches the bistable relay accordingly in the opposite direction, and writes the new switching state back into memory.
