  • Relay is designed to control the level of conductive liquids in wells, tanks, pools, tankers, reservoirs... (replacement HRH-1)
  • Galvanically isolated supply and guard circuits
  • Within one device, the following configurations can be selected: -
    • 2x one-level monitoring (in separate tanks)
    • 1x two-level monitoring (in one tank)
    • Pumping from one tank to another
  • DIP switch selection on the front panel (8 functions)
  • Adjustable probe sensitivity (for each probe separately)
  • Adjustable relay switching delay (for each probe separately
  • 10Hz watch frequency prevents polarization of the liquid and increases resistance to interference by network frequency
  • 2x output relay (with changeover contact 16A / 250V AC1)
  • 3-MODULE design, mounting onto DIN rail.
