Mitsubishi Electric FX Series - Quick Reference Matrixes

2.10.3 Quick Reference Matrixes
When only input/output extension blocks without a built-in power supply are added to a base
unit, a quick reference matrix can be used. The following examples are valid for base units of the
FX
3U series.
AC powered base units
In the following quick reference matrixes, the value at the intersection of the number of input
points to be added (horizontal axis) with the number of output points to be added (vertical axis)
indicates the remaining power supply capacity.
For FX
3U-16MR/ES, FX3U-16MT/ES, FX3U-16MT/ESS, FX3U-32MR/ES, FX3U-32MT/ES or
FX
3U-32MT/ESS:
쎲 Example
When a 16-input and a 16-output point extension block are connected to a base unit
FX
3U-16M첸 or FX3U-32M첸, the residual current of the 24V DC service power supply is
150 mA.
For FX
3U-48MR/ES, FX3U-48MT/ES, FX3U-48MT/ESS, FX3U-64MR/ES, FX3U-64MT/ES,
FX
3U-64MT/ESS, FX3U-80MR/ES, FX3U-80MT/ES, FX3U-80MT/ESS, FX3U-128MR/ES,
FX
3U-128MT/ES or FX3U-128MT/ESS:

Example
When a 32-input and a 16-output point extension block are connected to an AC powered
base unit with 48, 64, 80 or 128 I/Os, the 24 V DC service power supply can still deliver a
maximum current of 250 mA to other devices.
Confirm the current capacity of 24 V 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 function modules are con
-
nected, it is necessary to consider whether they can be powered by the remaining power supply
capacity.
