Handling of 24 V DC input
■Input terminal
For FX5U CPU module, input 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.

MELSEC iQ-F FX5 User's Manual (Application)
For input module (extension connector type) and input/output module
• FX5-CEX/D, FX5-C32ET/D
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.)

• FX5-CEX/DS, FX5-C32ET/DSS
In the sink input, the input (X) is turned on by connecting 24 V DC [+] with
the [COM] 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 LED corresponding to the DISP switch lights up.
(FX5-C16EX/DS does not have the DISP switch.)
