Current monitoring relay of Imin and Imax in 1P - AC/DC PRI-41

Monitors overcurrent or undercurrent in AC or DC circuits in 3 ranges, 2x independent output contacts
WINDOW

DESCRIPTION

  • Used to monitor overloading/relief (machine, motor, etc.), check consumption, diagnostics on a remote device (burning, short circuit, increased current draw, etc.)
  • Relay designed for monitoring DC and AC currents in three ranges.
  • the relay controls the current size in two independent levels (Imax, Imin). 
  • Setting the monitored level Imax (in % of range).
  • Setting the monitored level Imin. (in % of range - for PRI-42 - function WINDOW), (in % of the set upper limit - for PRI-41 - function HYSTERESIS).
  • 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: for each current level.
