/u003Cp dir=/u0022ltr/u0022/u003EAnother key feature of the IS220PPDAH1A board is that it allows for corrective action to occur by sending and reporting information but it cannot take directive protection action. This board supports system maintenance by sending timely information to the PDM. /u003Cstrong/u003EThe PPDA board can receive feedback from up to six PDM components, most of these components are JPDx boards and will host the PPDA I/O pack./u0026nbsp;/u003C/strong/u003E/u003C/p/u003E
/u003Cp dir=/u0022ltr/u0022/u003EThe IS220PPDAH1A board uses electronic IDs to determine power distribution information, the information will then be used to populate the IONet outputs and provide the correct information and feedback to the conjoining boards./u0026nbsp;/u003C/p/u003E

產(chǎn)品說明
配電反饋板IS220PPDAH1A是通用電氣公司生產(chǎn)的Mark VIe系列的一部分。該板是配電模塊的一部分，在這種配置下，它將為接地故障檢測、大容量電源健康、電源總線電壓和分支電路狀態(tài)提供反饋。該模型能夠具有完整的系統(tǒng)反饋和監(jiān)控，這使其不同于標準的配電方法。請注意，盡管該模型為分支電路提供反饋，但分支電路并不直接連接到PPDA組件。
IS220PPDAH1A板的另一個關鍵特性是，它允許通過發(fā)送和報告信息來采取糾正措施，但不能采取直接保護措施。該板通過向PDM及時發(fā)送信息來支持系統(tǒng)維護。PPDA板可以接收多達六個PDM組件的反饋，這些組件中的大多數(shù)是JPDx板，并將托管PPDA I/O包。
IS220PPDAH1A板使用電子id來確定配電信息，該信息將用于填充IONet輸出，并向連接板提供正確的信息和反饋。
請注意，當IS220PPDAH1A板用于讀取240伏交流電的應用中時，它不應與直流電壓交叉連接；當這種情況發(fā)生時，峰值電壓將超過MOV額定值并導致故障。由于大多數(shù)交流電源必須在中性點接地的情況下工作，所以會出現(xiàn)故障。
