RELATED PRODUCTS• PC configurator software (model: R8CFG)
Downloadable at our web site.
A dedicated cable is required to connect the module to thePC. Please refer to the internet software download site orthe users manual for the PC configurator for applicable
cable types.

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: 2 msec.
Input circuit time constant: Approx. 1 msec.
Data range: 0 – 10000 of the input range
Data allocation: 2
