Light-twilight-rain-wind sensor relay, 4 OptoMOS semiconductor outputs 50mA/8..230V UC
Light-twilight-rain-wind sensor relay, 4 OptoMOS semiconductor outputs 50mA/8..230V UC. Standby loss 0.05Â–0.5 watt only. Modular device for DIN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. Supply voltage 8 to 230V UC. The sensor relay LRW12D evaluates the signals from the light sensor LS, the rain sensor RS and the wind sensor WS and sends appropriate control signals to the downstream EGS12Z-UC or EGS12Z-UC actuators depending on the setting via the display on the front panel. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. A light sensor LS, rain sensor RS and wind sensor WS can be connected to a sensor relay LRW12D. However, only one per sensor. If one or two of the three possible sensors are not connected, OFF has to be selected in the function menu for the relevant sensor. However, at a wind sensor WS several LRW12D can be connected for controlling different wind speeds. Then the LRW12D must be connected to the same potential +B1/-A2. When the supply voltage UC (8-253V AC or 10-230V DC) is applied to B1/A2, the LRW12D can be set as described in the operating instructions.
