1 NO contact potential free 16A/250V AC with tungsten pre-contact. 230V LED lamps up to 600W, incandescent lamp load up to 3300W. Max. inrush current 500A/2ms. No standby loss. Modular device for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. With the patented Eltako Duplex technology (DX) the normally potential-free contacts can still switch in zero passage when switching 230V AC 50Hz and therefore drastically reduce wear. Simply connect the neutral conductor to the terminal (N) and L to 1(L) for this. This gives a standby consumption of only 0.1 Watt. Universal control voltage 8 to 230V UC. Low switching noise. No permanent power supply necessary, therefore no standby loss. By using a bistable relay coil power loss and heating are avoided even in the on mode. The relay contact can be open or closed during start-up. It is synchronised at first operation. The electronics does not have an internal power supply and therefore no power is consumed in any contact position. A control current flows only during a short control impulse of 0.2 seconds. This activates the microcontroller, reads the last switching state from the non-voltage memory, switches the bistable relay to its opposite state accordingly and rewrites the new switching state to memory.
