Voltage input characteristics
The following shows the list of the analog input ranges and the graphs of each voltage input characteristic, at the voltage
input.

User range setting
*1 If an analog input value exceeds the range of digital output value, the digital output value is fixed to the maximum or minimum value.

-10 to +10 V
User range setting
*2 Set the offset value and gain value in the user range setting within a range satisfying the following conditions. Failure to satisfy the
conditions may not result in proper A/D conversion.
Setting range of the offset value and gain value: -10 to +10 V
((Gain value) - (Offset value))  2.0 V
*3 Maximum resolution in the user range setting. The resolution reaches the maximum when (gain value - offset value) = 4 V. Even when
(gain value - offset value) < 4 V, the maximum resolution is unchanged.
• Set values within the practical range of the analog input and the digital output at each input range. If the
range is exceeded, the resolution and accuracy may not fall within the range of the performance
specifications. (Do not use the values in the dotted line region in the graph of voltage input characteristics.)
• Do not set the voltage over 15 V. Doing so can cause breakdown of components.
