如果使用220V的直流电源（蓄电池）给PLC供电，可以显著地减少来自交流电源的干扰，在交流电源消失时，也能保证PLC的正常工作。
若PLC电源模块选用DC24V供电模块，可以选用外加开关电源方式，如图1。
这样，就把电源方向的干扰挡在开关电源之外了，现场运行证明这种方案是切实可行并可靠的。
3.6模拟量输入部分
模拟量尽量采用4～20mA这种不易受电磁干扰的电流信号方式，模拟量输入无论屏内还是屏外均要求用屏蔽电缆接线，并且屏蔽层一端要可靠接地，否则，电磁干扰将影响模拟量采样值的正确性。同时，在采样算法中也应加入滤波算法剔除较短的峰值较大的脉冲干扰。

PLC应远离强干扰源，如高压开关柜、大功率可控硅装置、高频焊机和大型动力设备、动力线等。与PLC装在同一个屏内的电感性元件，如继电器、接触器的线圈，应并联RC消弧电路，以避免屏内强磁场的产生。
PLC的I/O线与大功率线应分开走线，如因条件限制实在要在同一线槽中布线，信号线应使用屏蔽电缆。交流线与直流线应分别使用不同的电缆，开关量、模拟量I/O线应分开敷设，后者应采用屏蔽线。不同类型的线应分别装入不同的电缆管或电缆槽中，并使其有尽可能大的空间距离。 |
