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 2 kΩ.
If external load resistance becomes larger than
2 kΩ, the output voltage will increase slightly.
When the load is 1 MΩ, 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.
