1 Introduction

The RemoDAQ-8000 Series is a set of intelligent sensor to
computer interface modules containing built in microproces­sor. They are remotely controlled through a simple set of
commands issued in ASCII format and transmitted in RS-485
protocol. They provide signal conditioning , isolation, ranging ,
A/D and D/A conversion, data comparison, digital commun­ication, timer/counter, wireless communication, collection
AC and other functions.

RemoDAQ-8031A RTD Module

RemoDAQ-8031A RTD input module supports one RTD
input channel for temperature measurement. This module can
accept 2 wire, 3 wire RTD sensor. The module offers signal
conditioning, A/D conversion, ranging, and RS-485 digital
communication functions.

RemoDAQ-8033A is a three channel RTD input module.

RemoDAQ-8034 is a four channel RTD input module

The common features of analog input modules are given as
following ：

z 16-bits sigma-delta ADC to provide excellent accuracy.
z 4-channels RTD direct connect
z Software calibration
