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.

digit: Digital output value
V: Analog input voltage (V)

(2) 0 to 5V
(3) -10 to 10V
(4) 0 to 10V
(5) 1 to 5V (extended mode)
 User range setting
*1 Set the offset value and gain value in the user range setting within a range that satisfies the following conditions. If the following
conditions are not satisfied, A/D conversion may not be performed properly.
Setting range of the offset value and gain value: -10 to 10V
((gain value) - (offset value))  1.6V
*2 Maximum resolution in the user range setting.
*3 When analog input exceeds the range of the digital output value, the digital output value is fixed to the maximum or minimum.

1 to 5V (extended mode)
User range setting
• Set values within the practical range of the analog input and digital output at each input range. If the values
are out of the range, the resolution and accuracy may not fall within the range of the performance
specifications. (Do not use values in the dotted line region in the graph of voltage input characteristics.)
• The range of 1 to 5V (extended mode) allows extending the lower limit value of analog input. The upper limit
value of analog input cannot be extended.
• Do not set the voltage over 15V. Doing so can cause breakdown of the elements.
