Monitoring voltage relay
HRN-42

Relay designed for monitoring DC and AC voltage in three ranges.

DESCRIPTION

  • The relay controls the size of the voltage in two independent levels (Umin, Umax).
  • Setting the monitored level Umax (in % of range.)
  • Setting the monitored level Umin (in % of range - for HRN-42 -function WINDOW), (in % of the set upper limit - for HRN-41 - function HYSTERESIS).
  • Adjustable function “MEMORY”.
  • Function of second relay (independently / in parallel).
  • Adjustable delay for eliminating short-term outages and surges for every level independently.
  • Galvanically separated power supply from monitoring inputs. 
  • Output contact 2x switching 16 A / 250 V AC1 for each monitored voltage level.
  • In 3-MODULE design, fi xing to DIN rail
