■ 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.
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.
