The PZ-829 Relays detect the presence of electrically conductive liquids at the installation levels of flood sensors. They maintain the minimum and maximum states of the controlled liquid within the area defined by the user.

Operation: After the liquid level drops to the minimum state (i.e., the MIN and COM electrodes are open), the MIN contact will switch to position 11-12, while the MAX contact remains in position 8-9. Upon reaching the maximum state (the MAX and COM electrodes are closed), the MIN relay contact switches to position 11-10 and the MAX contact to position 8-7.

The conductive sensors (3 pieces) are connected with a wire with a core diameter of up to 1 mm² and a maximum length of 100 m. Note! Terminals 4-5-6 are isolated from the network.
