Chapter14 Analog Output Module (XBF-DV04C/XBF-DC04C)
Accuracy of digital output value does not changed even if input range is changed. When digital input
range is selected with unsigned value, accuracy is ±0.2% (Ambient temperature of 25 ± 5 ℃)

(1) Accuracy when using -10~10V output
16000 × 0.2% = 32
Accuracy range when using -10V output will become
(-10V - 32×1.25㎷) ~ (-10V + 32×1.25㎷) = -10.04 ~ -9.96V,
Accuracy range when using 10V output will become
(10V - 32×1.25㎷) ~ (10V + 32×1.25㎷) = 9.96 ~ 10.04V
(2) Accuracy when using 4~20㎃ output
16000 × 0.2% = 32
Accuracy range when using 4㎃ output will become
(4㎃ - 32×1㎂) ~ (4㎃ + 32×1㎂) = 3.97㎃ ~ 4.03㎃
Accuracy range when using 20㎃ output will become
(20㎃ - 32×1㎂) ~ (20㎃ + 32×1㎂) = 19.97㎃ ~ 20.03㎃
