可编程控制器的分类及特点
（一）分类
（1）从组成结构形式分
①一体化整体式PLC
②模块式结构化PLC
（2）按I/O点数及内存容量分
①超小型PLC
②小型PLC
③中型PLC
④大型PLC
⑤超大型PLC
（3）按输出形式分
①继电器输出 为有触点输出方式，适用于低频大功率直流或交流负载
②晶体管输出 为无触点输出方式，适用于高频小功率直流负载
③晶闸管输出 为无触点输出方式，适用于高速大功率交流负载
（二）特点
①可靠性高、抗干扰能力强
②编程简单、使用方便
③设计、安装容易，维护工作量少
④功能完善、通用性好，可实现三电一体化 PLC将电控（逻辑控制）、电仪（过程控制）和电结（运动控制）这三电集于一体。
⑤体积小、能耗低
⑥性能价格比高
可编程控制器的应用
①开关量的逻辑控制
②位置控制
③过程控制
④数据处理
⑤通信联网
⑥CIMS的应用
