Regmet DZ4 Flood Sensor is designed for signalling fault conditions (e.g., water leakage) in heat exchange stations, boiler rooms, and similar facilities. The flood sensor is powered by a direct current voltage of 24 VDC, 24 VAC and includes output terminals of the open emitter and open collector type. Therefore, the signalling can be switched to the positive or negative pole of the supply voltage. The flood sensor is designed for DIN rail mounting. Suitable sensing probes are DS probes.

Function

Upon connecting the probe to the sensor input and joining the probe electrodes, the red LED on the front of the sensor lights up, and the outputs are activated or deactivated. The state of the outputs (activation/deactivation) is determined by switching the jumper to position A or B. The setting jumpers are accessible after removing the right side cover.
