Overall accuracy
Ambient temperature:
25±5°C
±0.5%(±50mV) for 10V full scale ±0.5%(±80μA) for 16mA full scale
Ambient temperature:
0 to 55°C
±1.0%(±100mV) for 10V full scale ±1.0%(±160μA) for 16mA full scale
Reference
Shipment adjustment is carried out by external
load resistance 2kΩ.
If external load resistance becomes larger than
2kΩ, the output voltage will increase slightly.
When the load is 1MΩ, 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.
