LRW12D-UC Eltako Data interface DIN rail
Light-twilight-rain-wind-sensor relay, 4 OptoMOS-semiconductor outputs. Standby loss only 0.05 to 0.5 watts. The sensor relay evaluates the signals of the light sensor LS, the rain sensor RS and the wind sensor WS and, depending on the setting, issues corresponding control commands to the downstream actuators via the display on the front. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. One LS light sensor, one RS rain sensor and one WS wind sensor can be connected to each sensor relay. Of each sensor, however, only one. If one or two of the three possible sensors are not connected, select OFF in the function menu for the respective sensor. However, several LRW12D can be connected to a wind sensor WS to control different wind speeds. The LRW12D must then be connected to the same potential +B1/-A2. As soon as the supply voltage UC is applied to B1/A2, the LRW12D can be adjusted according to the operating instructions.This text is machine translated.
