For input module (extension cable type), input/output module (extension cable type), powered input/output module, and high-
speed pulse input/output module
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.)
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.) In the source input, the input (X) is turned on by connecting 24 V DC [-] with
the [COM] terminal, and connecting a no-voltage contact or PNP 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.)
X0 to X17 of a CPU module can be used as RUN input terminals by setting parameters.

• Sink input • Source input
In the sink input, the input (X) is turned on by connecting 24 V DC [+] with
the [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 LED corresponding to the DISP switch lights up. In the source input, the input (X) is turned on by connecting 24 V DC [-] with
the [S/S] terminal, and connecting a no-voltage contact or PNP 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.
