Reference
If the external load resistance (Rs) is less than
5kΩ, the load will be increased as shown in the
following formula: (Increase: 100 mV per 1%)

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 inputs.
• Channels are not insulated from each other.
Number of I/O occupied
points
0 point (This number is not related to the maximum I/O points of the PLC.)
