3.12.1 Control Cards
The control cards are mounted inside the door of the controller distribution module (Figure 16).
The CXCP can accommodate up to eight digital input channels. These channels can monitor digital alarm/control
signals from rectifiers, converters and other types of equipment. Some of these channels are pre-assigned to
monitor specific signals. See the Software manual for more information.
Each CXCP contains eight standard and eight optional Form C alarm output relays to extend alarms and control
external apparatus. Each internally generated alarm or control signal may be mapped to any one of the 16 relays,
or, several signals may be mapped to just one relay or none at all.
Refer to the detailed as-built schematic that ships in your documentation package.
