●The total current consumption from the I/O
power supply must not exceed the
maximum current of the I/O power supply.
(NX Units that are supplied power from
external sources are not included in the
calculation.)
●The voltage drop in the I/O power supply
must be within the voltage specifications
of the I/O circuits of the NX Units and the
connected external devices.

•
The Additional I/O
Power Supply Unit is
used because
different I/O power
supply voltages are
used.
The Additional I/O Power
Supply Unit is used because
otherwise the maximum
current of the I/O power supply
would be exceeded.
