6SE6440-2UD27-5CA1 當有源輸入元件(霍爾開關(guān)、接近開關(guān)、光電開關(guān)、光幕傳感器等)數(shù)量比較多，消耗功率比較大，PLC內(nèi)置電源不能滿足時，需要配置外置電源。根據(jù)需求可以配24VDC，功率的開關(guān)電源。外置電源原則上不能與內(nèi)置電源并聯(lián)，根據(jù)COM與外部共線的特點， SINK(sink Current 拉電流)輸入方式時，外置電源與內(nèi)置電源正極相連接;SRCE(source Current 灌電流)輸入方式時，外置電源與內(nèi)置電源負極相連接。

簡單判斷SINK(sink Current 拉電流)輸入方式，只需要Xn端與負極短路，如果接口指示燈亮就說明是SINK輸入方式。共正極的光藕合器，可接NPN型的傳感器。SRCE(source Current 灌電流)輸入方式，將Xn端與正極短路，如果接口指示燈亮就說明是SRCE輸入方式。共負極的光藕合器，可接PNP型的傳感器。

 對于2線式的開關(guān)量輸入，如果是無源觸點，SINK與SRCE按上圖的輸入元件接法，對于2線式的接近開關(guān)，需要判斷接近開關(guān)的極性，正確接入。
