Connect Controller I/Os (C2)
Wire the digital and analog inputs and outputs according to the requirements of
your application.
Wire the digital and analog 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 19.
Connect the return of the 24 VDC supply to pin 1, 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 on both.
