PLC内部用光耦合器、输出模块中的小型继电器和光敏晶闸管等器件来实现对外部开关量信号的隔离,PLC的模拟量I/O模块一般也用光耦合器来实现隔离。这些器件除了能减少或外部干扰对系统的影响外,还可以保护CPU模块,使之免受从外部窜入PLC的高电压的危害,因此一般没有必要在PLC外部再设置干扰隔离器件。
在某些工业环境,PLC受到强烈的干扰。由于现场条件的限制,有时很长的强电电缆和PLC的低压控制电缆只能敷设在同一电缆沟内,强电干扰在输入线上产生的感应电压和感应电流相当大,足以使PLC输入端的光耦合器中的发光二极管发光,光耦合器的隔离作用失效,使PLC产生误动作。在这种情况下,对于用长线引入PLC的开关量信号,可以用小型继电器来隔离。开关柜内和距离开关柜不远的输入信号一般没有必要用继电器来隔离。
为了提高抗干扰能力和防雷击,PLC和计算机之间的串行通信线路可以考虑使用光纤,或采用带光耦合器的通信接口。
PLC的24 VDC电源回路与设备之间,以及120/230 VAC电源与危险环境之间,提供电气隔离。
