Wiring examples
• Sink wiring
The example is the wiring for the input/output of the FX5UC-32MT/D.
Fuse
When the input
points X000 to
X017 are used,
connect a pull-up
resistor (3.3 kΩ/
0.5 W).
FX5UC-32MT/D
• Source wiring
The example is the wiring for the input/output of the FX5UC-32MT/DSS.
Fuse
When the input
points X000 to
X017 are used,
connect a pull-
down resistor
(3.3 kΩ/0.5 W).
FX5UC-32MT/DSS
*1 The grounding resistance should be 100 Ω or less.
