Chapter 9 Analog Output Option Board (XBO-DA02A)
Accuracy for analog output value does not changed even if output range is changed. Figure below shows
the range of the accuracy with analog output range of 0 ~ 10 V and digital output type of unsigned value
selected.
Accuracy of XBO-DA02A is ±1.0%.

(1) Accuracy in case of 5V output
4000 × 1.0% = 40
So in case of 5V output, accuracy range is (5V - 40×0.0025V) ~ (5V+40×0.0025V) = 4.9 ~ 5.1V
(2) Accuracy in case of 10V
4000 × 1.0% = 40
So in case of 10V output, accuracy range is (10V-40×0.0025V) ~ (5V+40×0.0025V) = 9.9 ~ 10.1V
