(0 – 90 %)

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @1 minute (input to output

to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Range -10 – +10 V, Input Setting 1 – 5 V,

Output Range 0 – 20 mA, Output Setting 4 – 20 mA

■ Overall accuracy

• Input Accuracy = Input Range Span (20 V) ÷ Input Span

Setting (4 V) × 0.01 % = 0.05 %

• Output Accuracy = Output Range Span (20 mA) ÷ Output

Span Setting (16 mA) × 0.04 % = 0.05 %

Overall Accuracy = 0.05 + 0.05 = ±0.10 %
