Eltako 21110002 impulse switch electronic ES12-110-UC 8..230V UC 1S+1OE

1 normally open contact + 1 normally closed contact potential-free 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 8..230V UC at control input +A1/-A2 or 230V with up to 5mA glow lamp current at control input (L)/-A2 (N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No constant power supply required, therefore 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 power loss and no heating as a result, even when switched on. The relay contact can be open or closed when commissioned and synchronizes when first activated. The connection terminal assignment is identical to the electromechanical impulse switch S12-110-. If this impulse switch is in a circuit that is monitored with a FR12-230V field isolator, no additional base load is required, but the monitoring voltage of the FR12-230V must be set to max. The electronics do not have their own power supply and therefore do not consume any power in either contact position. The control current, which activates the microcontroller, only flows during the short control pulse of just 0.2 seconds. It reads the last switching state from its non-volatile memory, switches the bistable relay in the opposite direction accordingly and writes the new switching state back to the memory. combines the advantages of wear-free electronic control with the high performance of special relays.
