Description

• Under or Over voltage monitoring (selectable) • 5 Selectable voltage ranges (1V, 2V, 5V, 10V or 20V) • 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. Specification • Monitoring function: Under or Over voltage • Monitored voltage ranges: 0.1 – 1V, 0.2 – 2V, 0.5 – 5V, 1 – 10V or 2 – 20V AC/DC • Trip level: 10 – 100% of selected range • Hysteresis: 2 or 10% • Time delay: 0.1 – 30s • Aux. supply voltage*: 12 – 60V AC/DC or 24 – 230V AC/DC • Output: SPDT 8A @ 250V (AC1) • Dimensions(mm): W:17.5 x H:89 x D:66.5
