TCM via the "Aux Input" is the only available Trip Circuit monitor on non-expanded I/O units.
The TCM input is provided for monitoring the continuity of trip circuits. The input can be used for nominal trip coil
voltages of 24 Vdc – 250 Vdc. Trip circuit monitoring is performed in the active breaker status only (trip circuit
supervision when breaker is closed). Both the DC supply and continuity for the circuit is monitored.

The Breaker Monitor feature calculates an estimate of the per-phase wear on the breaker contacts by measuring
and integrating the current (or current squared) through the breaker contacts as an arc.
The per-phase values are added to an accumulated total for each phase, and then compared to a user-
programmed threshold value. When the threshold is exceeded in any phase, the relay can set a programmable
output contact.
The accumulated value for each phase can be displayed.
The Breaker Monitoring feature requires an initiating contact to begin accumulation, and the accumulation begins
after the set time delay.
