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.
