PLC对于电源线带来的干扰具有一定的抵制能力。在可靠性要求很高或电源干扰特别严重的环境中，可以安装一台带屏蔽层的隔离变压器，以减少设备与地之间的干扰。一般PLC都有直流24V输出提供给输入端，当输入端使用外接直流电源时，应选用直流稳压电源。因为普通的整流滤波电源，由于纹波的影响，容易使PLC接收到错误信息。
2.控制系统中干扰及其来源
现场电磁干扰是PLC控制系统中最常见也是最易影响系统可靠性的因素之一，所谓治标先治本，找出问题所在，才能提出解决问题的办法。因此必须知道现场干扰的源头。（1）干扰源及一般分类
影响PLC控制系统的干扰源，大都产生在电流或电压剧烈变化的部位，其原因是电流改变产生磁场，对设备产生电磁辐射；磁场改变产生电流，电磁高速产生电磁波。通常电磁干扰按干扰模式不同，分为共模干扰和差模干扰。共模干扰是信号对地的电位差，主要由电网串入、地电位差及空间电磁辐射在信号线上感应的共态（同方向）电压叠加所形成。共模电压通过不对称电路可转换成差模电压，直接影响测控信号，造成元器件损坏（这就是一些系统I/O模件损坏率较高的主要原因），这种共模干扰可为直流，亦可为交流。差模干扰是指作用于信号两极间的干扰电压，主要由空间电磁场在信号间耦合感应及由不平衡电路转换共模干扰所形成的电压，这种干扰叠加在信号上，直接影响测量与控制精度。 （2）PLC系统中干扰的主要来源及途径
1.强电干扰
PLC系统的正常供电电源均由电网供电。由于电网覆盖范围广，它将受到所有空间电磁干扰而在线路上感应电压。尤其是电网内部的变化，刀开关操作浪涌、大型电力设备起停、交直流传动装置引起的谐波、电网短路暂态冲击等，都通过输电线路传到电源原边。
