● Use the value within the practical analog input range and practical digital 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 graph of voltage input characteristics.)
● Do not set the voltage over ±15V. Doing so can cause breakdown of the elements.
(4) Current input characteristics
The following graph shows the current input characteristics.

*1 Set the offset value and gain value in the 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.
• Gain value ≤ 20mA, offset value ≥ -20mA
• ((Gain value) - (Offset value)) ≥ 16mA
• 20.84mA ≥ (Gain value - (Offset value × 2))
*2 When the analog input value exceeds the range of digital output values, the digital output value is fixed to the maximum
or minimum value.

*3 The extension A/D converter module does not support User range 2.
● Use the value within the practical analog input range and practical digital 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 graph of current input characteristics.)
● Do not set the voltage over ±30mA. Doing so can cause breakdown of the elements.
