Universal level switch for monitoring 1 to 6 levels HRH-9

Description 

• The relay is designed to control the level of conductive liquids in wells, sumps, tanks, pools, tankers, reservoirs ...
• Galvanically separated power and monitoring circuits
• Possibility to connect up to 6 level probes (+ one common probe)
• Each probe has its own output relay function selection for each probe separately 
• Adjustable delay after power on (START Delay)
• Adjustable relay closing delay (Probe Delay) - common for all probes
• Automatic calibration of the sensitivity of the probes according to the conductivity of the monitored liquid
• For probes 4, 5, 6 possibility of manual sensitivity adjustment
• A monitoring frequency of 10 Hz prevents polarization of the liquid and increases the resistance to mains frequency interference
