PERFORMANCE

Accuracy: Input accuracy + output accuracy
Inversely proportional to the span.
Except the accuracy of input resistor.
See CALCULATION EXAMPLES OF OVERALL ACURACY.
Input accuracy: (% of input range)
-1000 – +1000 mV : ≤ ±0.01 %
-10 – +10 V : ≤ ±0.01 %
0 – 50 mA : ≤ ±0.02 %
Output accuracy:  ±0.04 % of output range
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span
Response time: ≤ 1 sec. (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 Type -10 – +10 V, Input Range 1 – 5 V, Output Type -10 – +10 V, Output Range 1 – 5 V
• Input accuracy = Max. Input Range (20 V) ÷ Span (4 V) × 0.01 % = 0.05 %
• Output accuracy = Max. Output Range (20 V) ÷ Span (4 V) × 0.04 % = 0.2 %
Accuracy= ±0.25 %
