PERFORMANCE

Accuracy: Input accuracy + output accuracy
See CALCULATION EXAMPLES OF OVERALL ACURACY.
Inversely proportional to the span.
• Input accuracy
±0.2 %  of span or ±0.5°, whichever is greater.
Display accuracy
 Input display: Input accuracy ±1 digit
 Output display: Input accuracy + output accuracy ±1 digit
• Output accuracy: ±0.04 % of max. output range
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span
Input resolution: 6000 - 36000
Output resolution: Max. 16 bits
Response time: ≤ 0.5 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 Span 60°, Output Range 0 – 20 mA, Output Setting 4 – 20 mA
Overall accuracy
• Input Accuracy = Input (60°) × Input Accuracy (0.2 %) = 0.12°
  0.12°< 0.5° thus
  Input Accuracy = (0.5°) ÷ 60° × 100 = 0.83 %
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.04 % = 0.05 %
Overall Accuracy = 0.83 + 0.05 = ±0.88 %
