Conversion processing is performed at a speed of 80
The conversion accuracy is ± 0.1% (When the ambient temperature is 25 ± 5 °C).
The resolution mode can be changed according to the application, and digital-
value resolution settings of 1/4000, 1/12000 or 1/16000 can be selected.

The output range can easily be changed using GX Developer.
1 The output range refers to the type of offset/gain settings. The most
frequently used range is set as the default but the user can also specify their
own offset/gain settings.
This function sets a constant time (120
the digital value is written from the programmable controller CPU. Highly
accurate analog control can be achieved by combining this function with a
