Connect Machine I/Os (C3)
Wire the machine inputs and outputs according to the requirements of your
application.
Unused pins must remain unwired.
To preserve isolation of the digital I/Os, connect a 24 VDC source to pin 9.
Connect the return of the 24 VDC supply to pin 19, which functions as the
ground path for the outputs.
Note: The 24 VDC supply and return can be connected on either the Controller
interface (C2) or the Machine interface (C3), but it is not necessary to
connect it to both.
