PERFORMANCE

Conversion accuracy (in percentage of input range)

Voltage input:±0.05 %

Current input:±0.1 %

Conversion accuracy is inversely proportional to input span.

Conversion rate: 8 msec.

Input circuit time constant: Approx. 1 msec.

Data range: 0 – 10000 of the input range

(Scaling of converted data is configurable with the

configurator software)

Data allocation: 2

Module addresses in use: 2

Power output (input connector): Rated current 0.5 A DC per

channel (rated current 3 A for internal fuse (slow blow fuse

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

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 1500 V AC @ 1 minute

(input or exc. supply to internal bus or internal power to

ground)

CALCULATION EXAMPLES OF CONVERSION ACCURACY

■ Voltage input:

For input setting value 1 - 5 V DC

Conversion accuracy = Input range span (20 V) ÷ input

setting value span (4 V) × 0.05 (%) = 0.25 (%)

■ Current input:

For input setting value 4 - 20 mA DC

Conversion accuracy = Input range span (40 mA) ÷ input

setting value span (16 mA) × 0.1 (%) = 0.25 (%)

(Span is common for configuration mode and fixed input

mode)
