Current monitoring relay PRI-42

  • TO MONITOR OVERLOADING / DISCHARGE ( MACHINE, MOTOR…), LOAD SENSING, DIAGNOSTICS OF REMOTE DEVICE (INTERRUNPTION, SHORT CIRCUIT, CURRENT CUNSUMPTION INCREASE…)
  • MONITORING ADJUSTED CURRENT IN 2 INDEPENDENT LEVELS (OVERVOLTAGE/UNDERVOLTAGE).
  • MEMORY FUNCTION, “RESET” BUTTON ON THE FRONTAL PANEL..
  • FUNCTION OF 2ND RELAY (INDEPENDENT/PARALLEL).
  • ADJUSTABLE TIME DELAY TO ELIMINATE SHORT VOLTAGE DROPS AND PEAK.
  • SETTING THE UMAX LEVEL (IN% RANGE) AND THE MONITORED UMIN LEVELS (IN% OF THE SET UPPER LIMIT – FUNCTION WINDOW).
  • GALVANICALLY SEPARATED SUPPLY
Categories: , , ,

• 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)
• 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 changeover 16 A / 250 V AC1 for each current level
• 3-MODULE, DIN rail mounting
