Mounting: Surface or DIN rail

Weight: Approx. 200 g (0.44 lb)

PERFORMANCE (without linearization)

Accuracy: Input accuracy + output accuracy

Inversely proportional to the span.

Input accuracy (% of max. input range): ±1Ω or 0.05 %,

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

Refer to 'CALCULATION EXAMPLES OF OVERALL ACCURACY'.

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

(±0.008 %/°F)

Input resolution: Max. 18 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] Total Resistance 1000 Ω, Input Setting 100 – 600

Ω, Output Range 0 – 20 mA, Output Setting 4 – 20 mA

■ Overall accuracy

• Input Accuracy = Total Resistance (1000 Ω) ÷ Input Span

Setting (500 Ω) × 0.05 % = 0.1 %

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

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

Overall Accuracy = 0.1 + 0.05 = ±0.15 %
