PERFORMANCE in percentage of span

Overall accuracy:
Input accuracy + output accuracy [gain ≤ 1]
(inp. accuracy + out. accuracy) × gain [gain > 1]
Inversely proportional to the span.
See CALCULATION EXAMPLES OF OVERALL ACURACY.
• Input accuracy: (% of max. input range)
-1 – +1 V : ±0.01 %
-10 – +10 V : ±0.01 %
0 – 50 mA : ±0.02 %
• Output accuracy: ±0.04 % of max. output range
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span at -5 to +55°C [23 to 131°F]
Response time: (0 – 90 %)
Standard: ≤ 500 msec.

Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @1 minute (input to output

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Type -10 – +10 V, Input Range 1 – 5 V, Output Type 0 – 20 mA, Output Range 4 – 20 mA
Max. Input Range (20 V) ÷ Span (4 V) × 0.01 % = 0.05 %
Max. Output Range (20 mA) ÷ Span (16 mA) × 0.04 %
= 0.05 %
Overall accuracy = 0.05 + 0.05 = ±0.10 %
