PERFORMANCE in percentage of span

Accuracy: Input accuracy + output accuracy
Inversely proportional to the span.
Input accuracy in percentage of input span:
• ±0.01 % for -1000 to +1000 mV
• ±0.01 % for -10 to +10 V
• ±0.02 % for 0 to 50 mA
Output accuracy at max. frequency (FM):
• ±0.10 % for ≤ 10 kHz
• ±0.05 % for ≤ 5 kHz
• ±0.02 % for ≤ 1 kHz
• For 10 kHz to 100 kHz output accuracy is following.
 Output accuracy (%) = Max. frequency (kHz) x 0.01
Output accuracy (PWM): ±0.2 %
See CALCULATION EXAMPLES OF OVERALL ACCURACY.
Temp. coefficient: ±0.01 %/°C (±0.006 %/°F) of max. input span
Response time: 0.1 sec. + 1 pulse cycle of 100 % output
The time between the moment when the input changes 0 % to 100 % and the moment when the first pulse changes.
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

1. Frequency modulation
E.g.: Input range -10 to +10 V, input span 1 to 5 V, max. frequency 10 kHz
Input accuracy = Input range (20 V) ÷ Input span (4 V) x Input accuracy (0.01 %) = 0.05 %
Output accuracy = 0.10 %
Overall accuracy = ±0.15 %
2. Pulse width modulation
E.g.: Input range -10 to +10 V, input span 1 to 5 V, frequency 1 kHz
Input accuracy = 0.05 % (same as above)
Output accuracy = 0.20 %
Overall accuracy = ±0.25 %
