RC420 Rev.9 49
7. Expansion I/O Board - Optional
7.1 Expansion I/O Board
Install an expansion I/O board in an ISA slot in the Controller when extra inputs or
outputs are desired.
Each additional expansion I/O board provides 32 inputs and 32 outputs. The number of
I/Os that can be expanded is subject to the number of ISA slots available in the type of
Controller used.
The input and output bit #s are assigned as follows.
Input Bit # Output Bit # Applicable Hardware
0 to 15 0 to 15 Controller Standard I/O
48 to 79 48 to 79 The 1st Expansion I/O board
80 to 111 80 to 111 The 2nd Expansion I/O board

■
Use the PNP-type of protected Expansion I/O Board for CE conformance.
CAUTION
■ Be sure to wire the output circuit properly. Especially the expansion I/O board
has no protection circuitry for short-circuit and reverse-connection. Improper
wiring may cause malfunction of the parts on the board and then improper
function of the robot system.
