低通濾波器可以吸收掉電源中的大部分“毛刺”，如用L1和L2來表示用來抑制高頻差模電壓，L3和L4來表示用等長的導(dǎo)線反向繞在同一磁環(huán)上的，50Hz的工頻電流在磁環(huán)中產(chǎn)生的磁通互相抵消，磁環(huán)不會飽和。兩根線中的共模干擾電流在磁環(huán)中產(chǎn)生的磁通是迭加的，共模干擾被L3和L4阻擋。C1和C2來表示用來濾除共模干擾電壓，C3來表示用來濾除差模干擾電壓。R表示壓敏電阻，其擊穿電壓略高于電源正常工作時的zui高電壓，平常相當(dāng)于開路。遇尖峰干擾脈沖時被擊穿，干擾電壓被壓敏電阻鉗位，后者的端電壓等于其擊穿電壓。

高頻干擾信號不是通過變壓器的繞組耦合，而是通過初級、次級繞組之間的分布電容傳遞的。在初級、次級繞組之間加繞屏蔽層，并將它和鐵芯一起接地，可以減少繞組間的分布電容，提高抗高頻干擾的能力。
如果使用220V的直流電源（蓄電池）給PLC供電，可以顯著地減少來自交流電源的干擾，在交流電源消失時，也能保證PLC的正常工作。
若PLC電源模塊選用DC24V供電模塊，可以選用外加開關(guān)電源方式，如圖1。
