The Carlo Gavazzi DUB01 monitoring relay is a precise, one-phase, TRMS AC/DC overvoltage or undervoltage relay. The built-in latch function allows the relay output to be maintained in the ON position. The inhibit function can be used to avoid relay operation when not desired, such as during maintenance and transitions. The LEDs indicate the state of the alarm and the output relay.
