When the load voltage and external power supply are the same
This example is when the values of the rated load voltage and external power supply
for driving internal circuit are the same. In this situation, there is only one power supply.

Notes
Either positive or negative polarity is possible for the input
voltage supply.
The I/O number given above is the I/O number when the
expansion I/O unit is installed as the first expansion unit
(*section 5.3).
