Multifunction voltage monitoring relays AC/DC - HRN-39


EAN: 8595188184960 | Code: 8496


  • It is used to monitor the value of alternating or direct voltage in 1-phase circuits.
  • Supply voltage from monitored voltage.
  • Monitors voltage exceeding the upper voltage level (Umax) and falling below the lower voltage level (Umin) – according to the selected function.
  • Smooth adjustment of both voltage levels – the lower level Umin is set in % of the upper-level Umax.
  • Adjustable time delay (to eliminate short-term voltage drops and spikes).
  • Option to select functions with fault state memory (Latch).
  • The fault state memory can be reset by the control input (R).
  • Measures true root mean square value of the voltage - TRUE RMS


  • Overvoltage: Yes
  • Undervoltage: Yes
  • Monitored range: AC 24 - 150 V
  • Output contact: 1x CO, 16 A
  • Housing: 1-MODULE
  • Power supply: from monitored voltage
  • Dimensions: 90 x 17.6 x 64 mm (3.5˝ x 0.7˝ x 2.5˝)
