Using Intelligent Input Terminals Section 4-5
The two diagrams below show input wiring circuits using an external supply. If
using the "Sinking Inputs, External Supply" in below wiring diagram, be sure
to remove the short bar, and use a diode (*) with the external supply. This will
prevent a power supply contention in case the short bar is accidentally placed
in the incorrect position. For the "Sourcing Inputs, External Supply", please
connect the short bar as drawn in the diagram below.
