PZ-829 liquid level control relay
PZ-829
PZ-829 relays are used to detect the presence of electrically conductive liquids at flood probe mounting levels. They allow to maintain the minimum and maximum states of the controlled liquid within the range set by the user.
Operation
When the liquid level drops to the MIN state (i.e., MIN and COM electrodes open), the MIN contact is switched to the 11-12 position; the MAX contact remains in the 8-9 position. When the MAX state is reached (MAX and COM electrodes closed), the MIN relay contact is switched to the 11-10 position, and the MAX contact is switched to the 8-7 position.
Probe connection method
Electrode probes (3 pcs.) connected by a wire with a conductor diameter of up to 1 mm? and a maximum length of 100 m.
Note!
Terminals 4-5-6 are separated from the network.
