Handling of 24 V DC input
■Input terminal
For 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.

For input module (extension connector type) and input/output module (extension connector type)
• 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, the LED corresponding to the DISP switch lights up.(FX5-C16EX/D does not have the DISP switch.)

• Sink/source-input-common type
In the sink input, the input (X) is turned on by connecting 24 V DC [+] 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 24
V DC to close the circuit.
At this time, the input display LED turns on. For the module having DISP
switch, LED complying with DISP switch turns on.

• Source input
When a no-voltage contact or PNP open collector transistor output
is connected between an input (X) terminal and the [24V] terminal
and the circuit is closed, the input (X) turns on.
The input display LED turns on.
