任何信号都不要形成环路，如不可避免，让环路区尽量小。
每个集成电路一个去耦电容。每个电解电容边上都要加一个小的高频旁路电容。
用大容量的钽电容或聚酷电容而不用电解电容作电路充放电储能电容。使用管状电容时，外壳要接地。
1、采用性能优良的电源，电网引入的干扰
对于
PLC
控制器供电的电源，应采用非动力线路供电，直接从低压配电室的主母线上采用**线供电。选用隔离变压器，且变压器容量应比实际需要大1.2～1.5倍左右，还可在隔离变压器前加入滤波器。对于变送器和共用信号仪表供电应选择分布电容小、采用多次隔离和及漏感技术的配电器。 　　控制器和I/O系统分别由各自的隔离变压器供电，并与主电路电源分开。PLC控制器的24V直流电源尽量不要给外围的各类传感器供电,以减少外围传感器内部或供电线路短路故障对PLC控制器的干扰。此外，为保证电网馈电不中断，可采用在线式不间断供电电源（UPS）供电，UPS具备过压、欠压保护功能、软件监控、与电网隔离等功能，可提高供电的安全可靠性。对于一些重要的设备，交流供电电路可采用双路供电系统。
不同类型的信号分别由不同电缆传输，采用远离技术，信号电缆按传输信号种类分层敷设，相同类型的信号线采用双绞方式。严禁用同一电缆的不同导线同时传送动力电源和信号，避免信号线与动力电缆靠**行敷设，增大电缆之间的夹角，以减少电磁干扰。为了减少动力电缆尤其是变频装置馈电电缆的辐射电磁干扰，从干扰途径上阻隔干扰的侵入，要采用电力电缆。
