Multifunctional impulse switching relay, 1+1 normally open contact, potential-free 16A/250V AC, 230V LED lamps up to 400W, incandescent lamps 2000W, with DX technology. Bidirectional. Standby loss only 0.1-0.6 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Connection to the Eltako RS485 bus. Cross-wiring of bus and power supply with jumper. With the patented Eltako duplex technology, the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thus drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to K(L). This results in an additional standby loss of just 0.1 watt. The maximum current as a sum across both contacts is 16A at 230V. If the supply voltage fails, the device is switched off in a defined manner. If the 2 relays of the FMS14 are switched on, 0.6 watts are required. The sensors are taught in using 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 required function: 2S = impulse switch with 2 normally open contacts. (2xS) = 2-way impulse switch with one normally open contact each. WS = impulse switch with 1 normally open contact and 1 normally closed contact (standby loss 0.3W). SS1 = series switch 1 + 1 normally open contact with switching sequence 1. SS2 = series switch 1 + 1 normally open contact with switching sequence 2. SS3 = series switch 1 + 1 normally open contact with switching sequence 3. GS = group switch 1 + 1 normally open contact. 2R = switching relay with 2 normally open contacts. WR = switching relay with 1 normally open contact and 1 normally closed contact (standby loss 0.3W). RR = switching relay (closed-circuit relay) with 2 normally closed contacts (standby loss 0.5W). GR = group relay 1 + 1 normally open contact. Switching sequence SS1: 0 - contact 1(K-1) - contact 2(K-2) - contacts 1 + 2. Switching sequence SS2: 0 - contact 1 - contacts 1 + 2 - contact 2. Switching sequence SS3: 0 - contact 1 - contacts 1 + 2. Switching sequence GS: 0 - contact 1 - 0 - contact 2. GR: relay with alternately closing contact. The LED under the upper rotary switch accompanies the teach-in process in accordance with the operating instructions and indicates control commands during operation by flashing briefly.
