Multifunction Sensor Relay, 5 OptoMOS – 22500501

Multifunction sensor relay UC for brightness, twilight, wind, rain and frost. Stand-by loss without multi-sensor MS only 0.5 watt. The MSR12-UC multifunction sensor relay evaluates the signals from the multi-sensor MS once every second and issues corresponding control commands to the downstream actuators, depending on the setting of the rotary switches on the front panel. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. Only 1 multi-sensor MS can be connected to an MSR12-UC multifunction sensor relay. However, several MSR12-UCs can be connected to one multi-sensor MS, e.g. to be able to evaluate up to three cardinal directions with the light sensors of the MS. Only one MSR12-UC must have the external terminating resistor. For other MSR12-UCs, it must be removed. The power supply simultaneously supplies the multi-sensor MS connected to terminals MS1, MS2, MSA and MSB, including the heating of the rain sensor surface. After installation, wait for the automatic synchronization of approx. 1 minute. During this time, 3 LEDs light up in a calm sequence.
