Offset: Lower range can be any specific value within the

output range provided that the minimum span is

maintained.

(e.g. 4 – 20 mA: 300 Ω [6 V ÷ 20 mA])

■ DC Voltage: -10 – +10 V DC

Operational range: -11.5 – +11.5 V DC

Minimum span: 1 V

Offset: Lower range can be any specific value within the

output range provided that the minimum span is

maintained.

Load resistance: Output drive 1 mA max.

(e.g. 1 – 5 V: 5000 Ω [5 V ÷ 1 mA])

If not specified, the output range is shown below.

V2Z1: 1 – 5 V / 4 – 20 mA DC

PERFORMANCE

Overall accuracy:

Input accuracy + output accuracy [gain ≤ 1]

(inp. accuracy + out. accuracy) × gain [gain > 1]

Inversely proportional to the span.

See HOW TO CALCULATE THE ACCURACY.

• Input accuracy: (% of input range)

0 – 50 Ω : ±0.02 %

0 – 100 Ω : ±0.02 %

0 – 250 Ω : ±0.01 %

0 – 800 Ω : ±0.01 %

0 – 8 kΩ : ±0.02 %

• Output accuracy: (% of output range)

-10 – +10 V : ±0.02 %

0 – 20 mA : ±0.04 %

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of I/O range

at 0 to 55°C [32 to 131°F]

Response time: ≤ 0.9 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 1 or output 2 or

power to ground)

500 V AC @1 minute (output 1 to output 2 to power)

HOW TO CALCULATE THE ACCURACY

■ Overall Accuracy

[Example] Total resistance 800 Ω, 250 – 750 Ω input, 1 – 5 V

output

Input Accuracy

= Max. Range ÷ Input Span × Input Accuracy

= 800 ÷ 500 × 0.01

= 0.02

Output Accuracy

= Max. Range ÷ Output Span × Output Accuracy

= 20 ÷ 4 × 0.02 = 0.1

Overall Accuracy

= 0.02 + 0.1

= ±0.12 %
