一种高精度模拟信号分配模块的设计

Design of the High-precision analog signal distribution module

本文通过对模拟信号传输链路的研究,研制出0.1%精度的模拟信号分配模块。文章介绍了模块的应用需求背景,着重阐述了模块硬件设计思路。本模块采集标准的工业现场模拟信号,转化输出三路隔离的标准电流信号。在实际的应用中,具有测量精度高,抗干扰能力强,可靠性高,维护方便等诸多优点。

The paper,based on the analog signal transmission link of the research,developed the 0.1% precision analog signal distribution module. This article introduces the application background of the module, focuses on the hardware design. This module collects standard industrial analog signal into the output of the three channel standard current signal which are isolated between each other. In actual applications, the module has a lot of advantages such as the high measurement accuracy , high anti-interference ability, high reliability and easy maintenance etc.
