Calculate the total power consumption from the I/O power supply provided from an external source.
For the PNP (sourcing) type built-in output, an external source is required to supply power between
the common terminal and 0 V terminal in order to drive the internal circuits. When you calculate, in-
clude this power supply used to drive, too.
Refer to Input Specifications on page 3-14 and
Output Specifications on page 3-17 under 3-1-4 Termi-
nal Blocks on page 3-12 for the I/O specifications of the built-in I/O.
