The DIB02CB23150MV is a 1-phase precise true RMS AC/DC over or under current Monitoring Relay with SPDT contact. The current is measured through an external shunt. It can also be used as 1-phase and 3-phase current up to 500AAC can be monitored connecting MI or MP current transformers. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay. Current measuring through external shunt or CT Selection of measuring range by DIP-switches Measuring ranges from 6 to 150 mV AC/DC and 0.4 to 4Vp AC (MI or MP range) Adjustable current on relative scale Adjustable hysteresis on relative scale Adjustable delay function (0.1 to 30s) Programmable latching or inhibit at set level 22.5mm Euronorm housing LED indication for relay, alarm and power supply ON Galvanically separated power supply IP20 Protection rating Applications Industrial
