OUTPUT SPECIFICATIONS

■ DC Current

Maximum range: 0 – 20 mA DC

Minimum span: 1 mA

Conformance range: 0 – 24 mA DC

(Negative overrange current below 0 mA is not available.)

Offset: Lower range can be any specific value within the

output range provided that the minimum span is

maintained.

Load resistance: Output drive 12 V maximum

■ DC Voltage

Narrow Spans

Maximum range: -2.5 – +2.5 V DC

Minimum span: 250 mV

Conformance range: -3 – +3 V DC

Wide Spans

Maximum range: -10 – +10 V DC

Minimum span: 1 V

Conformance range: -11.5 – +11.5 V DC

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 maximum

INSTALLATION

Power Consumption

•AC:

Approx. 3 VA at 100 V

Approx. 4 VA at 200 V

Approx. 5 VA at 264 V

•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: ±0.03 % of input range (Table 2)

Output accuracy: ±0.03 % of output range (When the

output span is not more than 2 mA, add 0.1 % to the

accuracy)

The input accuracy is inversely proportional to the input

span; while the output accuracy is likewise inversely

proportional to the output span.

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

at -5 to +55°C [23 to 131°F]

Response time: 0.5 sec. + one pulse cycle or sampling time,

whichever is larger (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

to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Open collector input, 0 – 50 kHz; 1 – 5 V output.

Selected freq. range (100 kHz) ÷ Input span (50 kHz)×

Accuracy (0.03 %)= 0.06 % (Input accuracy)

Selected output range (20 V) ÷ Output span (4 V) ×

Accuracy (0.03 %)= 0.15 % (Output accuracy)

Overall accuracy = 0.06 + 0.15 = ±0.21 %
