Digital I/O module IOM040
These modules are suitable for all electronic trip units of the 6-series.
The digital I/O modules IOM040 provide two input and two output contacts for control and
remote signaling of alarms and tripping of the circuit breaker. They can be used for the
electronic trip units with display (6-series). Via the display of the ETU or the powerconfig
software, default settings of the inputs and outputs can be selected and configured.
Ready-to-close signaling switch for communication (COM RTC)
The ready-to-close signaling switch COM RTC provides the same information as the
ready-to-close signaling switch RTC, see Section Accessories for the auxiliary and signaling
switches (Page 80). It is used to query whether the circuit breaker is ready to close.
Unlike the RTC signaling switch, whose signals are available at the auxiliary conductor
terminal system, the signals of the ready-to-close signaling switch COM RTC are forwarded
via the communication link.
Actuator module (COM ACT)
The actuator module (COM ACT) is a communication link for the remote operation of
auxiliary solenoids (CC/ST). With the actuator module, the circuit breaker can be opened
and closed by remote access.
