8RO EXPANSION

BOARD

The

CPC 8RO

Expansion Board

optional

add-on board

available for

the

CPC L6O2

Monitor

and

Controt

Unit

(UCU). The

8RO

Expansion

Board

provides

the

L6O2

with

additional 8

Relayed

Outputs

(RO)

and

present 3

boards

may

added

to the

1602 UCU. Whether

locaI to

the

L602

on an

8RO

board, the

L6OZ

outputs are all

programmed and

operate

in the

same

way

as described

in the

nL6O2

Monitor

and Control

Systemrr manual.

The

8RO

connected

to the

6O2

way

of the

trExpansion

Communi-cation Bustt

l.lhich

means

the

8RO

boards can be

mounted where

the

devices being

controlled are located. This

rrremote

locationrr feature

will

decrease

the installation time

and

cost since only

communication

cable is reguired to

connect

the

8RO

to a

1-602

MCU.
