1 NO contact potential-free 16A/250V AC, 230V LED lamps up to 600W, incandescent lamps 2000W. No stand-by loss. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. With the patented Eltako Duplex technology (DX), the normally potential-free contacts can still switch in zero crossing when switching 230V AC 50Hz, thus drastically reducing wear. To do this, simply connect the N conductor to the terminal (N) and L to 1 (L). This results in a stand-by loss of only 0.1 Watt. If the contact is used to control switching devices which do not switch in zero-crossing themselves, (N) should not be connected, otherwise the additional closing delay will have the opposite effect. 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). Simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No permanent power supply required, therefore no stand-by 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 even when the unit is switched on. The relay contact can be open or closed at start-up and synchronises at the first actuation. The terminal assignment is identical to the electromechanical impulse switch S12-100-. If this impulse switch is in a circuit that is monitored with a FR12-230V field disconnector, no additional base load is required. However, the monitoring voltage of the FR12-230V must be set to max and control is only via A1-A2. The electronics have no power supply of their own and therefore no power consumption in either contact position. Only during the short control pulse of only 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 the memory.
