LINEARIZATION (/A only)

Type selection and data programming: PC Configurator

Software

• No Linearization: The output is proportional to the input.

• Segment Data: 100 points max. within the range of -15.00

to +115.00 % input or output represented as percentage of

full-scale

Low-end cutout: Low-end cutout point selectable within the

range of 0 to 100 %. For the input lower than the low-end

cutout point, the output signal equals 0 %.

• Square Root Extraction

Low-end cutout: Low-end cutout point selectable within the

range of 0 to 100 %. For the input lower than the low-end

cutout point, the output signal is linear to the input.

INSTALLATION

Power consumption

•DC: Approx. 3 W

Operating temperature: -25 to +65°C (-13 to +149°F)

Max. 55°C (131°F) for UL approval

Operating humidity: 0 to 95 %RH (non-condensing)

Mounting: DIN rail

Weight: 100 g (3.53 oz)

PERFORMANCE

Accuracy: Input Accuracy + Output Accuracy

Input accuracy: ±0.06 % of input range

Output accuracy: ±0.04 % of output range

(Input and output accuracy is inversely proportional to the

span)

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

Response time: ≤ 1 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 or power to ground)

500 V AC @ 1 minute (output to power)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input 4 – 20 mA, Output 4 – 20 mA

Input accuracy = Range 20 mA ÷ Span 16 mA × 0.06 % =

0.075 %

Output accuracy = Range 20 mA ÷ Span 16mA

× 0.04 % = 0.05 %

Overall accuracy = 0.075 + 0.05 = 0.13 %

(Segment gain < 1. Multiply the calculated result by the

gain when exceeding 1.
