Level relay HRH-5, 24-240 Vac/dc, for 1 - 2 electrodes

Relay is designed for monitoring levels in wells, basins, reservoirs, tanks,...

In one device you can choose the following configurations:

- One-level switch of conductive liquids (by connecting H and D).

- Two-level switch of conductive liquids.

One-state device monitors one level, two-state device monitors two levels (switches on one level and switches off on another level).

Adjustable time delay on the output (0.5 - 10s).

Sensitivity adjustable by a potentiometer (5 - 100 kΩ).

Measuring frequency 10 Hz prevents polarization of liquid and raising oxidation of measuring probes.

Galvanically separated supply voltage UNI 24 to 240 V AC/DC.
