jack.

Programmable features include:

•I/O type and range

•Zero and span adjustments

•Burnout

•User’s linearization table

Configurator connection: 2.5 dia. miniature jack;

RS-232-C level

INPUT SPECIFICATIONS

•Potentiometer: 0 – 50 Ω through 10 kΩ

If not specified, the input range is 1500 Ω.

Minimum span:

(Range) 0 – 50 Ω : 2.5 Ω

0 – 150 Ω : 5 Ω

0 – 300 Ω : 5 Ω

0 – 500 Ω : 5 Ω

0 – 1500 Ω : 150 Ω

0 – 10 kΩ : 1000 Ω

Reference voltage: 2.5 V (2.5 kΩ connected in serial)

Reference resistance: 2.5 kΩ

Excitation voltage:

2.5 × Connected Resistance ÷ (Connected Resistance +

2500) [V]

[Example] Resistance = 1000 Ω

2.5 × 1000 ÷ (1000 + 2500) = 0.7 [V]

See CALCULATION EXAMPLES OF OVERALL ACURACY.

• Input accuracy: (% of range)

0 – 50 Ω : ±0.02 %

0 – 150 Ω : ±0.02 %

0 – 300 Ω : ±0.01 %

0 – 500 Ω : ±0.01 %

0 – 1500 Ω : ±0.01 %

0 – 10 kΩ : ±0.01 %

• Output accuracy: ±0.04 % of max. output range

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

Response time: ≤ 1 sec. (0 – 90 %)

Burnout response time: ≤ 1 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

to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Total Resistance 0 – 1 kΩ, Output Range 1 – 5 V

Max. Input Range (1.5 kΩ) ÷ Span (1 kΩ) × 0.01 % = 0.015

%

Max. Output Range (20 V) ÷ Span (4 V) × 0.04 % = 0.2 %

Overall accuracy = 0.015 + 0.2 = ±0.22 %
