■Input circuit
• 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.

■Input sensitivity
For input signal current and Input sensitivity current of the CPU module, refer to Page 34 Input Specifications.
For input signal current and Input sensitivity current of the I/O modules, refer to Page 193 Input specifications.
■Display of operation
The LED turns ON when the photocoupler is driven.
With FX5-C32EX/D(S) or FX5-C32ET/D(SS), the LED target is switched with the DISP switch.
