三菱PLC采用漏输入，输入端本来就设计为对地短路就引发开入有效！年限制电流大小。不会对电源系统构成危害，最多只影响自己的回路。也不会由于电源故障影响其他输入回路的正常工作！
     对于PLC的开关量输入回路。我个人感觉日本三菱的要好得多，甚至比西门子等赫赫大名的PLC都要实用和可靠！其主要原因是三菱等日本PLC从欧美那儿学来技术并优化设计，作到：
而很多欧美PLC采用源输入方式，有一定弊端（当然有的PLC可选择源、漏输入！）
采用源输入，是共电源输入端。在工程实际应用中往往有太多的电缆，你可能无法保证电缆的相互接触、破损，说不定共电源的开关量线路会无意接触到设备地、外壳、其他地电位。因此可能断路电源供应回路。
造成电源损坏或者烧掉保险，从而可能影响其他输入回路的正常工作。除非，每个输入回路加保险……应用成本较高也容易出现其他故障！
