I/O characteristics
Specifications FX2N-5A
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.
• Channels are not insulated from each other.
Number of I/O points
occupied
8 points (Taken from either the input or output points of the PLC.)
