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
*1 Input impedance
• For the FX5UC CPU module, input module (extension connector type), and I/O module (extension connector type)
*1 Input impedance
*2 Connected to the [S/S] terminal instead of the [COM] terminal depending on the module
• RUN terminal setting
X0 to X17 of the CPU module can be used as RUN contact terminals by setting parameters.
For details, refer to the following.
MELSEC iQ-F FX5 User's Manual (Application)
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.
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 [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.)
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.
