三菱PLC采用漏輸入，輸入端本來就設(shè)計(jì)為對(duì)地短路就引發(fā)開入有效！年限制電流大小。不會(huì)對(duì)電源系統(tǒng)構(gòu)成危害，最多只影響自己的回路。也不會(huì)由于電源故障影響其他輸入回路的正常工作！
對(duì)于PLC的開關(guān)量輸入回路。我個(gè)人感覺日本三菱的要好得多，甚至比西門子等赫赫大名的PLC都要實(shí)用和可靠！其主要原因是三菱等日本PLC從歐美那兒學(xué)來技術(shù)并優(yōu)化設(shè)計(jì)，作到：
而很多歐美PLC采用源輸入方式，有一定弊端（當(dāng)然有的PLC可選擇源、漏輸入?。?br />
采用源輸入，是共電源輸入端。在工程實(shí)際應(yīng)用中往往有太多的電纜，你可能無法保證電纜的相互接觸、破損，說不定共電源的開關(guān)量線路會(huì)無意接觸到設(shè)備地、外殼、其他地電位。因此可能斷路電源供應(yīng)回路。
造成電源損壞或者燒掉保險(xiǎn)，從而可能影響其他輸入回路的正常工作。除非，每個(gè)輸入回路加保險(xiǎn)……應(yīng)用成本較高也容易出現(xiàn)其他故障！
