Select the input/output extension block (number of points) to be connected
to the main unit.
Check that the number of input/output points can be added.
When connecting the FX
3U
-1PSU-5V extension power supply unit to a system where the nearest
upstream unit to the FX
3U
-1PSU-5V is a main unit, include the current consumption by the input
extension blocks connected to the FX
3U
-1PSU-5V when calculating the total current consumption
of the main unit.

-16MR/ES, the
current of the 24V DC service power supply becomes 150 mA or less.

Confirm the current capacity of 24V DC service power supply from the value
shown in the quick reference matrix.
This remaining power supply capacity (current) can be used as a power supply to external loads
(sensors or the like) by the user.
When special adapters and special function units/blocks are connected, it is necessary to consider
whether they can be covered by this remaining power supply capacity.
