PERFORMANCE

Conversion accuracy (in percentage of input range)
±0.05 % (@ input range -10 - +10 V)
Conversion accuracy is inversely proportional to input span.
  Conversion accuracy computation example:
  When input range is 1 - 5 V: conversion accuracy = nominal input span (20 V) ÷ input span (4 V) × 0.05(%) = 0.25 (%).
Nominal input span is the same as the span at input range
 -10 - +10 V DC.
Conversion rate: 8 msec.
Input circuit time constant: Approx. 1 msec.
Data range: 0 – 10000 of the input range
Data allocation: 2
Module addresses in use: 4
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength:
  500 V AC @ 1 minute (input 1 to input 2 to input 3 to
  input 4 to input 5 to input 6 to input 7 to input 8)
  1500 V AC @ 1 minute (input to exc. supply to internal bus 
  or internal power to FG)
