Terminals A18 to A29 are analog inputs on the C3-1 Centurion main I/O module. Accepts

voltage signals within the range of (0 to 5) VDC or (4 to 20) mA and are compared to con-

troller set points or events.

Means by which the Centurion controller communicates with C3-3 Display and MConfigPro

to receive and transfer new or updated configurations and firmware; and ensure data and

configuration synchronization.

s User defines normal operating range for the controller to optimize the equipment. Set

points can also define some other threshold, exception or event that may require action.

Multiple set points are often applied to a process and they may be manipulated as needed

to meet changing conditions.

Terminals 30 to 61 are the digital input channels. User selects whether digital input is nor-

mally open (N/O), or normally closed (N/C). Users may also associate these inputs with

transition times for indicating no-flow conditions on divider blocks.
