Surge current relay with 4 channels, isolated from the supply voltage, with DX technology. Bidirectional. Stand-by loss only 0.1 watt. Connection to the Eltako RS485 bus. Cross-wiring bus and power supply with jumper. 230V LED lamps can be switched up to 400 watts per NO contact and up to a maximum inrush current of 25A/100ms. To do this, simply connect the N conductor to the clamp (N) and L to K(L). This results in an additional standby loss of only 0.1 watt. If all 4 relays of the F4SR14-LED are switched on, 1 watt is required. If the supply voltage fails, it is switched off in a defined way. The channels can be taught in independantly of each other as A SINGLE AND/or SINGLE channel.This text is machine translated.
