4.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。
