Carlo Gavazzi Monitoring Relay Voltage 1-Phase Din-Rail DUB71CB23500V

Carlo Gavazzi Monitoring Relay 1-Phase True RMS AC/DC Over or Under Voltage, DIN-Rail, SPDT, 2-500VAC/DC, Supply: 115/230VAC.

DUB71 is a precise TRMS AC/DC over or under voltage (selectable by DIP switch) monitoring relay. Owing to the built-in latch function, the ON-position of the relay output can be maintained. 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. 35.5 mm wide housing suitable both for back and front panel mounting
