Time required for
conversion
•FX
3U/FX3UC Series PLC :
80μs for each selected input channel + 40μs for each selected output channel
(Operation synchronized with sequence program)
•FX
3G Series PLC :
90μs for each selected input channel + 50μs for each selected output channel
(Operation synchronized with sequence program)

I/O
characteristics
Insulation
method
• The photocoupler is used to insulate the analog input and output area from the PLC.
• The DC/DC converter is used to insulate the power supply from the analog input and output area.
• Channels are not insulated from each other.
