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