Set the offset value and gain value in the user range setting within the range satisfying the following two conditions:
• Setting range: 0 to 20mA
• ((Gain value) - (Offset value)) 11.4mA
*2
The extension D/A converter modules does not support User range setting 2.
Use the value within the practical digital input range and practical analog output range. If a value is out of the range, the
maximum resolution and accuracy may not fall within the range of performance specifications. (Do not use the value in the
dotted line region in the above graph.)
