Overvoltage/Overcurrent monitoring relay. Carlo Gavazzi monitoring relays can also be used as 1- or 3-phase overcurrent monitoring relays when connected to MI or MP current transformers. Thanks to the integrated locking function, the ON position of the relay output can be maintained. The red LED indicates the alarm status. AC/DC overvoltage monitoring relays with selectable measurement range via DIP switch. Measurement ranges: 2 to 20 V AC/DC, 5 to 50 V AC/DC, 20 to 200 V AC/DC, 50 to 500 V AC/DC, 0.4 to 4 Vp AC. Adjustable voltage limit on a relative scale, adjustable hysteresis, programmable locking at set level. Output: 8 A, normally open 1-pole switching relay. LED display for relay and power supply ON. Galvanically isolated power supply. Panel and screw connection options available.
