High Side/Low Side Interfaces
The following interfaces are the same for the High Side and the Low Side I/O boards.
MISC I/O Power
The high side board and the low side board interface is designed to operate at
+24VDC nominal. The 24 VDC operation may be provided by the user or internally by
the robot. When provided by the user, the inputs are optically isolated. If user power
is not supplied, the board automatically switches to on-board power. With on-board
power, however, the ground isolation is defeated. See
for wiring the exter-
nal or internal power. Also see 3-Options Shown Wiring Diagram in Chapter 12.
NOTE:
All power and grounds within a connector are internally jumpered together. Out-
put circuits require that 24V power be applied.
The input and output pins provide for either user supplied power which guarantees
