Reference
Shipment adjustment is carried out by external
load resistance 2k
Ω.
If external load resistance becomes larger than
2k
Ω, the output voltage will increase slightly.
When the load is 1M
Ω, the output voltage is
about 2% higher than the correct value.

Output characteristics
Caution:
An area of dead band is located in the region of
0V. Therefore the output analog value may not
represent the digital value accurately.
Insulation method
• The analog output area is not insulated from the PLC.
