See CALCULATION EXAMPLES OF OVERALL ACCURACY.
Inversely proportional to the setting span.
Except the accuracy of input resistor.
Input accuracy: (% of max. input range)
-1000 – +1000 mV : ±0.01 %
-10 – +10 V : ±0.01 %
0 – 50 mA : ±0.02 %
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 (% of max. I/O range): ±0.015 %/°C
(±0.008 %/°F)
Input resolution: Max. 16 bits
Output resolution: Max. 16 bits
Response time (filter time constant: 0 sec.): ≤ 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 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 %
