Liquid level control relay with sensitivity adjustment PZ-828 RCB F&F

Product description

The liquid control relay serves as a component of the installation. The relay is designed to detect the liquid at given levels. The minimum and maximum stages can be easily set on the relay. When the minimum condition is detected, the device automatically turns on and fills the given water tank to the indicated maximum mark. Any malfunction is indicated by lighting a red LED on the front of the device. The electrode probe is connected by a wire with a diameter of 1mm2. Assembly as well as connection is not demanding. The main element of the relay is mounted on a mounting rail, to which the entire electrical system can be connected.

The connection of the relay can be made in series or in parallel. Serial connection consists in the arrangement of checking the phase wires simultaneously at multiple levels then the sensor will signal the problem. While the parallel connection of the relay will allow to switch on the alarm already after the detection of at least one, any connected sensor.
