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专用线供电。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、采用多次隔离和屏蔽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。
