Input wiring example

AC power supply type
■FX5S CPU module, FX5UJ CPU module, and FX5U CPU module
• Sink input
Ex.
For the FX5U CPU module
FX5U-32MT/ES
5V 0V 24V
FX5-16EX/ES
5V 0V 24V
FX5-16EX/ES
5V 0V 24V
*1 Handle the power supply circuit properly in accordance with "Power Supply Wiring".
*2 For an input device having a parallel resistance or a two-wire proximity switch, a bleeder resistance may be required.
*3 For sink input wiring, short-circuit the [S/S] and [24V] terminals of the CPU module.
The 24VDC service power supply or external power supply can be used for all inputs (X) of the CPU module.
However a user needs to select either one for each CPU module or I/O module. Both power supplies cannot
be used together in the same module.
