• 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
X000 to X017 of the CPU module can be used as RUN input terminals
by setting parameters.
MELSEC iQ-F FX5 User's Manual (Application)
• Function of input circuit
The primary and secondary circuits for input are insulated with a photocoupler, and the second circuit is provided with a C-R filter.
The C-R filter is designed to prevent malfunctions caused by chattering of the input contact and noise from the input line.
Input has a response delay switching from ON to OFF and OFF to ON, shown in the following table.

• Change of filter time
All input circuits have digital filters, and the input response time shown in the following table can be added by setting parameters.
When using this product in an environment with much noise, set the digital filter.
