Display of operation
The LED turns ON when the photocoupler is driven.
With FX5-C32EX/
 or FX5-C32ET/  , the LED target is switched with the DISP switch.
• FX5-C32EX/  : Smaller number (F)/Larger number (L)
• FX5-C32ET/  : Input (IN)/Output (OUT)
• 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.
