Rainwater level control relay 230V 16A 35mm PZ-828RC-WD

Detects electrically conductive liquids at the level of the flood probe installation.

How does the rainwater level control relay work?
In a dry condition, the relay contact remains in position 7-4. When the probe is flooded with liquid (i.e. the probe electrodes are short-circuited), the relay contact is switched to position 7-8. After the liquid level drops (opening of the probe electrodes), the relay contact returns to position 7-4.
 

Method of connecting the probe
The design of the probe allows it to be mounted on a flat, horizontal surface, e.g. on the floor in a room with hydro valves, flow pipes or in a laundry room. Thanks to this, it is possible to quickly detect a failure (flooding the room with liquid) while switching off electrical circuits or activating sound or light signals (alarm).< br />
The probe cable can be extended to 100 m.

Up to 10 probes can be connected to input 5-6 - in series or in parallel:
