1.12. Controller Wiring Terminals

DCM 200 Controllers consist of two main circuit boards, a Main circuit board and an LCD driver board.

The Main circuit board is located in the rear half of the enclosure and supports 3 analog sensor inputs, 2

digital inputs and 5 digital Outputs. The digital outputs consist of 3, 120VAC relays and 2, DC contacts.

It is connected to a single 2 line x 16 character LCD driver board and backlit LCD display mounted on the

back of the lid. The Ethernet jack and USB port are integral to the Main PCB.

Controllers may be supplied prewired with either 120VAC

receptacle cords, or ready to be installed with conduit and

individual wiring. Shown below are pictorial diagrams of

how to install cable glands into the bottom of the DCM 200

enclosure.

The diagrams show how to best open and install fittings in

the rear, then the front entrances on the bottom of the

enclosure.

Enclosure Entries

Caution 1:

Remove the controller frame assembly prior to drilling additional

enclosure entries to prevent damage to wiring and circuit boards.

The frame assembly is secured by 4 Phillips screws.

Caution 2:

Do not put conduit entries in the top of the enclosure.

Resulting conduit condensation and failure to seal may damage

controller circuit boards.

Sensor wiring in the same conduit with AC power will cause

measurement errors and measurement instability.
