6.5.5 Quick reference matrix [when only input/output devices are added]
(AC Power Supply/AC Input Type)
The following matrix shows the expandable units up to the
{
mark, where the desired inputs (horizontal axis)
and outputs (vertical axis) intersect.
Caution
When FX
2N
-8ER and FX
2N
-8ER-ES/UL are added, refer to Subsection 6.5.6.
Select the input/output extension block (number of points) to be connected
to the main unit
Since the AC power supply/AC input type main unit does not have a built-in service power supply, use an
external power supply to connect a DC input type extension block.
Also take into account the limitations on the number of expansion I/O points that can be added to an AC
power supply/AC input type main unit. 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.
AC power supply/AC input type
1) FX
3U
-32MR/UA1
(These main units do not have a built-in 24V DC service power supply.)
(Example) When adding 16 inputs to FX
3U
-32MR/UA1, a maximum of 32 outputs are expandable.
2) FX
3U
-64MR/UA1
(These main units do not have a built-in 24V DC service power supply.)
(Example) When adding 32 inputs to FX
3U
-64MR/UA1, a maximum of 40 outputs are expandable.
