Handling of 24VDC input
■Input terminal
• For the FX5S CPU module, FX5UJ CPU module, FX5U CPU module, input module (extension cable type), input/output
module (extension cable type), powered input/output module, and high-speed pulse input/output module
Sink input
When a no-voltage contact or NPN open collector transistor output is
connected between an input (X) terminal and the [0V] terminal and the circuit
is closed, the input (X) turns on.
The input display LED turns on.

Sink-input-dedicated type
When a no-voltage contact or NPN open collector
transistor output is connected between an input (X)
terminal and the [COM] terminal and the circuit is
closed, the input (X) turns on.
At this time, an LED corresponding to the DISP
switch lights up. (FX5-C16EX/D does not have the
DISP switch.)

Sink input
In the sink input, the input (X) is turned on by
connecting 24VDC [+] with the [COM] terminal or
[S/S] terminal, and connecting a no-voltage contact
or NPN open collector transistor output between
the input terminal and 24VDC to close the circuit.
At this time, the input display LED turns on. For the
module with the DISP switch, an LED
corresponding to the DISP switch turns on.

In the source input, the input (X) is turned on by
connecting 24VDC [-] with the [COM] terminal or
[S/S] terminal, and connecting a no-voltage contact
or PNP open collector transistor output between
the input terminal and 24VDC to close the circuit.
At this time, the input display LED turns on. For the
module with the DISP switch, an LED
corresponding to the DISP switch turns on.
