Conversion accuracy (in percentage of input range)
±0.1 % (@ input range -20 - +20 mA)
Conversion accuracy is inversely proportional to input span.
Conversion accuracy computation example:
When input range is 4 - 20 mA: conversion accuracy =
nominal input span (40 mA) ÷ input span (16 mA) × 0.1(%)
= 0.25 (%).
Nominal input span is the same as the span at input range
-20 - +20 mA DC.
Conversion rate: 2 msec.
Input circuit time constant: Approx. 1 msec.
Data range: 0 – 10000 of the input range
Data allocation: 2
Module addresses in use: 1
Max. consumption current: 100 mA
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength:
1000 V AC @ 1 minute (input 1 to input 2 to exc. supply to
internal bus or internal power to FG)
1000 V AC @ 1 minute (for modules combined with this
device)
