1）可编程控制器有继电器输出、晶闸管输出、晶体管输出三种形式。
可编程控制器（plc）具有结构灵巧，硬件配置灵活方便、可靠性高、抗干扰能力强，易学易用的特点，已作为普遍的自动化控制器件广泛应用于各行各业。《plc原理及应用》课程已成为工科院校一门覆盖面较广的***课，作为学校如何培养出高素质应用型plc人才，这成为社会、学校、教师与家长关注的焦点。根据多年的教学实践，就影响plc人才培养的各个因素的提高与协同
系统的设计结构合理，采用多圈值编码器采集水位，以可编程控制器为控制核心，提高了系统的自动化程度，保证了系统运行的可靠性；硬件、软件模块化设计具有良好的扩展性和灵活性，可根据现场实际需求更改系统的配置规模。该系统在福建水东电站现场运行表明工作稳定，在监视报警、综合计算、信号输出等各方面满足电站的运行要求，取得了很好的效果，有较高的推广价值
与个人计算机相比，plc在标准化方面作得较差：plc的软、硬件体系结构是封闭的而不是开放的；绝大多数plc使用专用的总线、专用通信网络及协议；各种plc产品的编程语言在表示方式、寻址方式和语法结构上都不一致，使得它们互不兼容。国际电工***会的iec6113l-3《可编程序控制器的编程软件标准》为plc编程的标准化铺平了道路。不少厂家正在开发以pc(个人计算机)为硬件平台、在WINOOWs操作系统下、符合iec61131-3国际标准的新一放体系结构的plc。
相对于国际的plc厂商而言，国内公司的plc应用业绩较少，用户对国产plc的性能、产品质量和技术支持持怀疑态度
