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.
