Overvoltage and overcurrent monitoring relays. Carlo Gavazzi monitoring relays can also be used as 1-phase or 3-phase overcurrent monitoring relays when connected to MI or MP current transformers. Thanks to the integrated latching function, the ON position of the relay output can be maintained. The red LED indicates the alarm status. AC/DC overvoltage monitoring relay selection of measurement range by 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 relative scale, adjustable hysteresis, programmable latching at record level. Output: 8 A, normally off-load 1-pole changeover relay. LED indication for relay and power supply ON. Galvanically isolated power supply. Panel and screw terminal options available.
