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

In one device you can choose the following confi gurations:
– one-level swotch 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)

Choice of function PUMP UP, PUMP DOWN

Adjustable time delay on the output (0.5 – 10s)

Sensitivity adjustable by a potentiometer (5-100kΩ)

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

Galvanically separated supply voltage UNI 24.. 240 VAC/DC

Output contact 1xchangeover/SPDT 8A/250V AC1

In 1-module type, mounting onto a DIN rail
