Item Specifications
A/D conversion circuit
driving power
24V DC +20%-15%, 40mA
(It is necessary to connect a 24V DC power supply to the terminal block.)
Interface driving power
5V DC, 15mA
(Since the internal power is supplied from the FX Series main unit, it is not
necessary to supply the power.)

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.
