Product DescriptionOrdering Key
DUB 01 C B23 10V
DUB01 and PUB01 are pre- ciseTRMS AC/DCoveror under voltage (selectable by DIP-switch) monitoring relays.
Owing to the built-in latch function, the ON-position of the relay output can be
maintained.Inhibitfunction can be used to avoid relay operation when notdesired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.
