■Input circuit
• Function of an input circuit
The primary and secondary circuits for input are insulated with 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 input line.
Input has a response delay switching from ON to OFF and OFF to ON, shown in the following table.

Input response time
(H/W filter delay)
• 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.

■Input sensitivity
For the input signal current and input sensitivity current of the CPU modules, refer to Page 32 Input Specifications.
For the input signal current and input sensitivity current of the I/O modules, refer to Page 160 Input specifications.
■Display of operation
The LED turns ON when the photocoupler is driven.
With FX5UC-MT/D(SS), FX5-C32EX/D(S) or FX5-C32ET/D(SS), the LED target is switched with the DISP switch.
• FX5UC-MT/D(SS), FX5-C32ET/D(SS): Input (IN)/Output (OUT)
• FX5-C32EX/D(S): Smaller number (F)/Larger number (L)
Precautions for connecting input devices
■In the case of no-voltage contact
Use input devices appropriate for low electric current.
If no-voltage contacts for high current (switches) are used, contact failure may occur.
■In the case of input device with built-in series diode
The voltage drop of the series diode should be the following value or less.
Also make sure that the input current is over the input-sensing level while the switches are on.
