HRH-5:Level switch

  • relay is designated for monitoring levels in wells, reservoirs, pools, tanks.......
  • In one device you can choose the following configurations:
  • - one-level switch for conductive liquids ( by connecting H and D)
  • - two-level switch for 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 utput (0,5 - 10sec)
  • sensitivity adjustable by a potentiometer (5-100k Ω)
  • 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 A/250V C1
  • in 1-module type, mounting onto a DIN rail
