This chapter describes the Input/Output (I/O) modules used with the
ROC800 and expansion backplanes and contains information on
installing, wiring, and removing those modules.
4.1 I/O Module Overview
The I/O modules typically consist of a terminal block for field wiring
and connectors to the backplane. Each I/O module uses a removable
terminal block to electrically connect to field wiring. Refer to Figures
4-1 and 4-2.
Note: Figure 4-2 represents a ROC827 with one EXP.
