Product Description Ordering Key
DUB 71 C B23 10V
DUB71 is a precise TRMS AC/DC over or under volt- age (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 suit- able both for back and front panel mounting.
