The Network Control Unit (NCU) is a field panel housing

electronic modules, terminal blocks, and signal conditioners

(pneumatic, linevoltageand electronic) all inside a single

enclosure.

The NCU contains the user-programmable main processor—the

Network Control Module (NCM)—for supervisory functions over

all devices on the local bus, and a combination of the

optional Digital Control Module and Point Multiplex Modules

to directly control field devices that wire to the NCU

termination blocks. This application installs all models of

the NCM(101, 102, 401, 200) into standard 1-Slot, 2-Slot, or

5-Slot base frames.
