Current monitoring relay of Imin and Imax in 1P - AC/DC PRI-42
Monitors overcurrent or undercurrent in AC or DC circuits in 3 ranges, 2x independent output contacts
HYSTERESIS
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.
