SOURCING CIRCUITS (PNP)
If the output devices can only source current (some PLC outputs
are this way), connect the “-” terminals to the ground of the DC
power supply that powers the output circuits. Then connect the
signals to the “+” terminals.
Note: We refer to an input as being ON or CLOSED when current is
flowing through the input. A signal is OFF or OPEN when no
current is flowing. An input is OPEN when the “+” and “-” input
terminals are at the same voltage, or when the input is left
unconnected.
