裝電線。

The triplicated I/O bus transfers data

between the I/O modules and the main

processors at 375 kilobits per second.

The triplicated I/O bus is carried along

the bottom of the backplane. Each

channel of the I/O bus runs between

one of the three main processors and

the corresponding channels on the I/O

module.

The I/O bus can be extended between

chassis using a set of three I/O bus

cables.

Communication Bus

The communication (COMM) bus

runs between the main processors and

the communication modules at 2

megabits per second.

Power for the chassis is distributed

across two independent power rails

down the center of the backplane.

Every module in the chassis draws

power from both power rails through

dual power regulators. There are four

sets of power regulators on each input

and output module: one set for each of

the channels A, B and C and one set for

the status-indicating LED indicators.

Field Signals

Each I/O module transfers signals to or

from the field through its associated

field termination assembly. Two positions in the chassis tie together as one

logical slot. The first position holds the

active I/O module and the second position holds the hot-spare I/O module.

Termination cables are connected to the

top of the backplane. Each connection

extends from the termination module to

both active and hot-spare I/O modules.

Therefore, both the active module and

the hot-spare module receive the same

information from the field termination

wiring.
