Weight: 150 g (0.33 lb)

PERFORMANCE in percentage of span
Overall accuracy: Input accuracy + output accuracy
• Input accuracy: Accuracy (Table 1) + Cold Junction Compensation Error 3°C (5.4°F)
• Output accuracy: Max. Output Range ÷ Span × ±0.04%
Cold junction compensation error:
±3°C at 25 ±10°C
±5.4°F at 77 ±18°F
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span
Response time: ≤ 1 sec. (0 – 90 %)
Burnout response: ≤ 10 sec.
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
1 to output 2 to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] K thermocouple, 0 – 1000°C, 4 – 20 mA DC output
Absolute value accuracy (Table 1): 0.25°C
CJC error (3°C) added: 3.25°C
• Input accuracy = 3.25°C ÷ 1000°C × 100 = 0.325 %
Output span: 16 mA (20 – 4)
• Output accuracy = 20 mA ÷ 16 mA × 0.04 = 0.05 %
Overall accucracy including CJC error = 0.325 + 0.05 = ±0.38 % of span
