INSTALLATION

Power Consumption

•AC:

≤ 5 VA for 100 – 120 V

≤ 7 VA for 200 – 240 V

Operating temperature: -5 to +55°C (23 to 131°F)

Operating humidity: 10 to 85 %RH (non-condensing)

Mounting: Surface or DIN rail

Weight: Approx. 200 g (0.44 lb)

PERFORMANCE

Accuracy: Input accuracy + output accuracy

See CALCULATION EXAMPLES OF OVERALL ACURACY.

Inversely proportional to the span.

• Input accuracy

±0.2 % of span or ±0.5°, whichever is greater.

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: ±0.015 %/°C (±0.008 %/°F) of max. span

Input resolution: 6000 - 36000

Output resolution: Max. 16 bits

Response time: ≤ 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 Span 60°, Output Range 0 – 20 mA, Output

Setting 4 – 20 mA

■ Overall accuracy

• Input Accuracy = Input (60°) × Input Accuracy (0.2 %) =

0.12°

0.12°< 0.5° thus

Input Accuracy = (0.5°) ÷ 60° × 100 = 0.83 %

• Output Accuracy = Output Range Span (20 mA) ÷ Output

Span Setting (16 mA) × 0.04 % = 0.05 %

Overall Accuracy = 0.83 + 0.05 = ±0.88 %
