The MI-DCMO control output module is used to provide either a single alarm circuit or Form C relay.

The MI-DCMO can be used to operate dry contacts for door holders, air handling unit shut down or other similar functions. Optionally the module can be used to supervise wiring to the ouput load providing monitoring of the external load voltage or power supply. If the monitored voltage falls below threshold then a fault condition will be indicated.

Each MI-DCMO uses one of the ninety-nine possible module addresses available on a loop. It responds to regular polling from the conrtol panel indicated by a pulsing LED every successful communication. On command from the control panel the MI-DCMO will disconnect the supervision and connect the external power supply across the load. The disconnection of the supervision provides a positive indication to the control panel that the relay is activated. The MI-DCMO has a built-in isolator which may be switched out if required.

The MI-DCMO uses a unique mechanical design allowing each module to be mounted either in a wall box (M200-SMB) or on a DIN rail (using M200- DIN). Irrespective of the mounting method chosen, the address switch is both visible and accessible for selection.

To help engineers in the maintenance and fault finding process, both the LEDs and the address switches can be viewed without having to remove the cover of the mounting box. The LEDs, being multi colour, provide diagnostic information regarding the status of the output. For ease of installation, testing and maintenance, the field wiring terminals are of a plug in design.
