EQUIPMENT DESCRIPTION
2-18
There are two circuit boards attached to the outside of the card cage:
- the System Interface and Driver Board, and
- the GC Controller's Terminal Board for Field Wiring.
The GC Controller's Terminal Board for Field Wiring provides termination connections for these
items:
- Communication ports (COM1, COM2, COM3, COM4, COM5, COM6, COM7, and
COM8),
- Analog inputs and outputs,
- Digital inputs and outputs,
- Controller-Analyzer interconnections,
- Parallel printer port, and
- Optional stream switching assemblies.
See drawing DE-20782 for an illustration of the GC Controller's Terminal Board for Field
Wiring.
The GC Controller's Terminal Board for Field Wiring also has sockets for transient protection
modules, and a 250 VAC, 2A fuse (5 x 20 mm) that protects all of the boards from transient surges.
See Appendix C and drawing CE-18115 for a list of transient suppression modules that are
installed for various configurations of the GC Controller and its communication, analog
output, and stream-switching options.
