PERFORMANCE

Overall accuracy:

Input accuracy + output accuracy [gain ≤ 1]

(inp. accuracy + out. accuracy) × gain [gain > 1]

Inversely proportional to the span.

Except the accuracy of input resistor.

See CALCULATION EXAMPLES OF OVERALL ACURACY.

• Input accuracy: (% of max. input range)

-1 – +1 V : ±0.02 %

0 – 50 mA : ±0.02 %

• Output accuracy: (% of output range)

-10 – +10 V: ±0.02 %

0 – 20 mA: ±0.04 %

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of I/O range

at 0 to 55°C [32 to 131°F]

Response time: ≤ 0.9 sec. (0 – 90 %)

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength:

1500 V AC @1 minute (input to output 1 or output 2 or

power to ground)

500 V AC @1 minute (output 1 to output 2 to power)

HOW TO CALCULATE THE ACCURACY

■ Overall Accuracy

[Example] 1 – 5 V input, 1 – 5 V output

Input Accuracy

= Max. Range ÷ Input Span × Input Accuracy

= 20 ÷ 4 × 0.01 = 0.05

Output Accuracy

= Max. Range ÷ Output Span × Output Accuracy

= 20 ÷ 4 × 0.02 = 0.1

Overall Accuracy = 0.05 + 0.1 = ±0.15 %
