MSR12-UC Eltako Input module DIN rail
UC multi-function sensor relay for brightness, twilight, wind, rain and frost. Stand-by loss without multi-sensor MS only 0.5 watt. The multi-function sensor relay MSR12-UC evaluates the signals of the multi-sensor MS once every second and, depending on the setting of the rotary switches on the front side, issues corresponding control commands to the downstream actuators. The OptoMOS semiconductor outputs switch the voltage applied to the universal voltage input terminal +B1. Only 1 multi-sensor MS can be connected to a multi-function sensor relay MSR12-UC. However, several MSR12-UC can be connected to a multi-sensor MS, in order to be able to evaluate e.g. up to three cardinal directions with the light sensors of the MS. Only with a MSR12-UC the external terminating resistor must be present. For other MSR12-UC, however, it must be removed. The power supply unit simultaneously supplies the MS multisensor 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 quiet sequence.This text is machine translated.
