Appendix 3 I/O Conversion Characteristic of A/D Conversion
*1 Set the offset value and gain value in user range setting within the range satisfying the following conditions.
If the following conditions are not satisfied, A/D conversion may not be properly performed.
• Setting range for offset value and gain value: -10 to 10V
• ((gain value)-(offset value)) ≥ 4.0V
*2 When analog input is performed exceeding the range of digital output value, the digital output value is fixed to the
maximum or minimum.
*3 This is the maximum resolution in user range setting.
● Use the value within the practical analog input range and practical digital output range. If a value is out of the range, the
resolution and accuracy may not fall within the range of performance specifications. (Do not use the value in the dotted
line region in the graph of voltage input characteristic.)
● Do not input a value of ±15V or more. This may damage the elements.
