Rainwater Level Relay Dual Status with Sensitivity Control 2x16A IP20 Mounting on a 35mm Rail PZ 829RC WD/FIF

The PZ-829 relays detect the presence of electrically conductive liquids in the mounting levels of floodlight probes. They keep the minimum and maximum values of the controlled liquid within the range set by the user. How it works: when the liquid level falls into the MIN state (i.e. MIN and COM electrodes open), the MIN contact is switched to position 11-12; the MAX contact remains in position 8-9. When the MAX state is reached (MAX and COM electrodes closed), the MIN relay contact is switched to position 11-10 and the MAX contact is switched to position 8-7. Probe connection method: electrode probes (3 pieces), connected by a cable with a conductor diameter of up to 1 mm² and a maximum length of 100 m. The clamps 4-5-6 are separated from the net.
