Light-twilight-rain-wind sensor relay, 4 OptoMOS semiconductor outputs 50mA/8..230V UC. Stand-by loss only 0.05-0.5 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Supply voltage 8..230V UC. The sensor relay LRW12D evaluates the signals from the light sensor LS, the rain sensor RS and the wind sensor WS and, depending on the setting, issues the corresponding control commands to the downstream actuators EGS12Z-UC or EGS12Z2-UC via the display on the front. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. One light sensor LS, one rain sensor RS and one wind sensor WS can be connected to one LRW12D sensor relay. However, only one of each sensor. If one or two of the three possible sensors are not connected, OFF must be selected in the function menu for the sensor in question. However, several LRW12Ds can be connected to one WS wind sensor to control different wind speeds. The LRW12Ds must then be connected to the same potential +B1/-A2. As soon as the supply voltage UC (8-253V AC or 10-230V DC) is applied to B1/A2, the LRW12D can be set up according to the operating instructions.
