Level switch HRH-5

• Relay is designed for monitoring levels in wells, basins, reservoirs,
tanks…
• In one device you can choose the following confi gurations:
– 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).
• Choice of function PUMP UP, PUMP DOWN.
• 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.. 240 V AC/DC.
• Output contact 1x changeover/SPDT 8A/250V AC1.
• 1-MODULE, mounting onto DIN rail
