Three-phase electrical energy meter F4SR14-LED

DIN railRS-485

4-channel impulse switch with integrated relay function, 1 NO contact per channel up to 8A/250V AC, 230V LED lamps up to 400W, incandescent lamps 1800 watts, potential free from the power supply, with DX technology. Bidirectional. Only 0.1 watt standby loss. Modular device for DIN-EN 60715 TH35 rail mounting. 2 modules = 36mm wide, 58mm deep. Connection to the Eltako-RS485 bus. Bus cross wiring and power supply with jumper. 230V LED lamps can be switched up to 400W and up to a maximum inrush current of 25A/100ms per NO contact. Patented Eltako Duplex technology allows you to switch normally potential free contacts in zero passage switching when 230V A/C voltage 50Hz is switched. This drastically ­reduces wear. To achieve this, simply connect the N conductor to the terminal (N) and L to K(L). This results in an additional standby consumption of only 0.1 watt. When all 4 relays of the F4SR14-LED are switched on, a power of 1 watt is required. If supply voltage fails, the device is switched off in defined mode. The channels can be taught-in as ES and/or ER channel separately from each other. Scene control: Several channels of one or several F4SR14-LED devices can be switched on or off in a scene by one of the four signals of a pushbutton with double rocker taught-in as a scene pushbutton.
