Multifunctional sensor relay UC for brightness, twilight, wind, rain and frost. Standby loss without multisensor MS only 0.5 watts. The multifunctional sensor relay MSR12-UC evaluates the signals from the multisensor MS once every second and issues corresponding control commands to the downstream actuators depending on the setting of the rotary switch on the front. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. Only 1 multisensor MS can be connected to a multifunctional sensor relay MSR12-UC. However, several MSR12-UC can be connected to a multisensor MS in order to be able to evaluate up to three directions with the light sensors of the MS, for example. The external terminating resistor only has to be present with one MSR12-UC. For additional MSR12-UC, however, it must be removed. The power supply simultaneously supplies the MS multisensor connected to terminals MS1, MS2, MSA and MSB, including heating of the rain sensor surface. After installation, wait for automatic synchronization (approx. 1 minute). During this time, 3 LEDs light up in quiet sequence.
