7.3.3 Expansion I/O Board : Output Circuit
The following diagrams illustrate cases where #48 through #79 (for the first Expansion
I/O Board) are assigned to the Expansion I/O Board’s inputs and outputs. The I/O
number assignment depends on the software settings.
Expansion I/O Board
I/O Typical Output Circuit Application 1:
Output #48 to #55 (the 8 points from the first point in among the 32 points in a
board)
CAUTION
■
Be sure to wire the output circuit properly because it 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.
