Multifunction surge current relay, 1+1 normally open contact potential-free 16A/250V AC, incandescent lamps 2000W, with DX technology. Bidirectional. Stand-by loss only 0.1-0.6 Watt. Series installation device for mounting on mounting rail. Connection to the Eltako RS485 bus. Cross-wiring bus and power supply with jumper. 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. Maximum current as total over both contacts 16A at 230V. If the supply voltage fails, it is switched off in a defined way. If the 2 relays of the FMS14 are switched on, 0.6 watt is required. The sensors are taught in with the upper and middle rotary switches. For normal operation, the middle rotary switch is then set to AUTO and the lower rotary switch to the desired function. The LED below the upper rotary switch accompanies the programming process according to the operating instructions and indicates control commands during operatio
