.I/O模块

各I/O点的通/断状态用发光二极管（LED）显示，PLC与外部接线的连接一般用接线端子，某些模块使用可以拆卸的插座型端子板，不需断开端子板上的连接线，就可以迅速的更换模块。

输入模块：PLC通过输入模块来接收和采集输入信号，通过输出模块控制接触器、电磁阀、电磁铁、调速装置等执行器，PLC控制的另一类外部负载是指示灯、数字显示装置和报警装置等。输入电路中设有RC滤波电路，以防止由于输入触点抖动或外部干扰脉冲引起的错误输入信号。

输出模块：输出模块的率放大元件有大功率晶体管和场效应管（驱动直流负载）、双向可控硅（驱动交流负载）和小型继电器，继电器可以驱动交流负载或直流负载。输出电流的典型值为0.5—2A，负载电源由外部现场提供。
