Input 
characteristics

Insulation method

• The photocoupler is used to insulate the analog input area from the PLC.
• The DC/DC converter is used to insulate the power supply line from the analog input area.
• Channels are not insulated from each other.

Number of I/O 
points occupied

0 points

(This number is not related to the maximum number of input/output points of the PLC.)
