Input terminal
For FX5UJ CPU module, input module (extension cable type), input/output module (extension cable type) and powered input/
output module
For input module (extension connector type) and input/output module (extension connector type)
• Sink-input-dedicated type
• Sink/source-input-common type
• Sink input
• Source 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.
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.
• RUN terminal setting
X0 to X17 of the CPU module can be used as RUN input terminals by setting parameters. For FX5UJ-24M
, X0 to X15 can be used.
MELSEC iQ-F FX5 User's Manual (Application)
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 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.
In the source 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 PNP 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.
