固态继电器及其应用

SOLID STATE RELAY (SSR) AND ITS APPLICATIONS

随着科技进步和工业发展，通过微机来实现自动控制已得到广泛应用。作为计算机与外界接口的装置，用交流固态继电器是最为理想的。本文重点介绍直流技入型固态继电器的基本结构、主要参数选用及其典型应用。

With the rapid development of science and industly,automatic control by computer has been wildly used. AC-SSR is one of the best interface components which has been used between computer and its outer instruments. This article focuses on the basic structure,choosing of main parameters and the tipical applications of AC-SSR
