When configuring a Class B, the DCM-4 has two (2) addresses. If address No.1 is set, input circuit No.1 (NO1, C1) will be
addressed as No.1, and input circuit No.2 (NO2, C2) will automatically be addressed as No.2. Refer to the figure below for an
example of wiring a Class B DCM-4.

Twin Relay Module – 4 inch mount (TRM-4)
The TRM-4 has two (2) contacts that are active simultaneously when TRM-4 is in the active mode. Normal output is nonpower-
limited, unless the power supply connected to the TRM-4 is power-limited and the circuits are power-limited.

Monitored Output Module – 4 inch mount (MOM-4)
If the power supply connected to the MOM-4 is power limited, then the outputs are power limited. The MOM-4 module may be
wired as a releasing device. Examples of a MOM-4 wired as a conventional and a releasing application are provided here.
