External digital I/O module IOM300
The external digital I/O module IOM300 provides 11 input and 10 output contacts for control
and remote signaling of alarms and tripping of the circuit breaker.
It is suitable both for the electronic trip units of the 6-series and of the 3-series because it is
connected directly to the CB1 and CB2 terminals of the auxiliary conductor terminal system.
