Chapter 7 Analog Input Module (XBF-AD08A)
7.5 Accuracy
Accuracy of digital output value does not changed even if input range is changed. Figure below
shows the range of the accuracy with analog input range of 0 ~ 10 V and digital output type of
unsigned value selected.
Accuracy of XBF-AD08A is ±0.5%.

[ Accuracy ]
(1) Accuracy when using 5V input
4000 × 0.5% = 20
Therefore the range of the accuracy will become (2000-20) ~ (2000+20) = 1980 ~ 2020
when using 5V input.
(2) Accuracy when using 10V input
4000 × 0.5% = 20
Therefore the range of the accuracy will become (4000-20) ~ (4000+20) = 3980 ~ 4020
when using 10V input.
