Control Relay - LMCVR / 500V ( Multifunction, Combined Voltage Monitoring )

• Under or Over voltage monitoring (selectable)
• 5 Selectable voltage ranges (20V, 50V, 100V, 200V or 500V)
• Adjustable Trip level, Hysteresis and Time delay + Latch
• Isolated Auxiliary supply
• SPDT Relay output
• 17.5mm wide, DIN Rail mount
• UL Listed

The product is designed to monitor voltage across a load (for example). An auxiliary supply (required to power the unit) must be present for the product to function.

Two monitoring modes available:

Under voltage:
In normal operation, the relay is in the energised state (monitored voltage above the set trip level). When the voltage decreases below the trip level, the relay will de-energise after the set delay. The voltage must increase above the trip level plus the hysteresis before the relay will re-energise.

Over voltage:
In normal operation, the relay is in the energised state (monitored voltage below the set trip level). When the voltage increases above the trip level, the relay will de-energise after the set delay. The voltage must decrease below the trip level minus the hysteresis before the relay will re-energise.
