7.3.3 Expansion I/O Board : Output Circuit
The following diagrams illustrate cases where #48 through #79 are assigned to the
Expansion I/O's inputs and outputs.
EPSON RC+ settings.
Expansion I/O Board
I/O Typical Output Circuit Application 1 :
Output #48 to #55 (Eight low numbers among thirty-two bit numbers existing in
one board are output.)
■ 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.
