KL3458型和PNP型傳感器在工控、自動(dòng)化行業(yè)是應(yīng)用非常廣泛傳感器輸出信號(hào)，如接近開(kāi)關(guān)。故名思意，這種傳感器都是以NPN和PNP三極管為主體，輸出是OC形式，在接plc的時(shí)候需要接電阻上拉或者下拉。下面介紹一下和PLC的接線(xiàn)方式。

1. NPN型傳感器和PLC的接線(xiàn)方式

NPN型傳感器一般具有三個(gè)輸出引腳，分別是電源正、電源負(fù)和信號(hào)線(xiàn)。在和PLC連接時(shí)，將電源正接PLC的24V，電源負(fù)接COM，而信號(hào)線(xiàn)則和PLC的數(shù)字輸入口DI連接，并在該口上接上拉電阻。
