简介： 在工业自动化领域，可编程控制器(PLC)作为自动控制以成为大多数自动化系统的设备基础，同时也给工业控制带来了前所未有的非凡变化。使用PLC的工业控制系统与传统的用继电器的工业控制系统相比，在操作、控制、效率和精度等各个方面都具有无法比拟的优点。虽然在工业控制系统中所使用的继电器控制设备不会被完全淘汰，但是由于PLC的出现已经改变了工业控制设计者的设计思想. 一、控制继电器存在的缺点　　今天继电器已应用到家庭及工业控制的各个领域。他们比以往的产品具有更高的可靠性。但是，这也是随之带来的一些问题。如绝大多数控制继电器都是长期磨损和疲劳工作条件下进行的，容易损坏。而且继电器的触点容易产生电弧，甚至会熔在一起产生误操作，引起严重的后果。再者，对一个具体使用的装有上百个继电器的设备，其控制箱将是庞大而笨重的。在全负荷运载的情况下，大的继电器将产生大量的热及噪声，同时也消耗了大量的电能。并且继电器控制系统必须是手工接线、安装，如果有简单的改动，也需要花费大量时间及人力和物力去改制、安装和调试。　二、可编程序控制器的优势、特点及功能　　可编程控制器以体积小功能强大所著称，它不但可以很容易地完成顺序逻辑、运动控制、定时控制、计数控制、数字运算、数据处理等功能，而且可以通过输入输出接口建立与各类生产机械数字量和模拟量的联系，从而实现生产过程的自动控制。特别是现在，由于信息、网络时代的到来，扩展了PLC的功能，使它具有很强的联网通讯能力，从而更广泛地应用于众多行业。
