A/D conversion

Voltage input
The graph below shows the conversion characteristics during voltage input and the accuracy against the maximum A/D
conversion value. Excluded when the wiring is influenced by noise.

digit: A/D conversion value V: Analog input voltage (V)
(1) Fluctuation range
(2) Practical analog input range
The maximum resolution and accuracy during the voltage input are shown below.
Input range setting
-9.9 to 9.9V
*1 The maximum and minimum A/D conversion values are as follows.
Input range setting
-9.9 to 9.9V
• Use within each practical analog input range and practical A/D conversion value range. If the range is
exceeded, the resolution and accuracy may not fall within the range of the 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.
