/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

产品说明
配电反馈板IS220PPDAH1A是通用电气公司生产的Mark VIe系列的一部分。该板是配电模块的一部分，在这种配置下，它将为接地故障检测、大容量电源健康、电源总线电压和分支电路状态提供反馈。该模型能够具有完整的系统反馈和监控，这使其不同于标准的配电方法。请注意，尽管该模型为分支电路提供反馈，但分支电路并不直接连接到PPDA组件。
IS220PPDAH1A板的另一个关键特性是，它允许通过发送和报告信息来采取纠正措施，但不能采取直接保护措施。该板通过向PDM及时发送信息来支持系统维护。PPDA板可以接收多达六个PDM组件的反馈，这些组件中的大多数是JPDx板，并将托管PPDA I/O包。
IS220PPDAH1A板使用电子id来确定配电信息，该信息将用于填充IONet输出，并向连接板提供正确的信息和反馈。
请注意，当IS220PPDAH1A板用于读取240伏交流电的应用中时，它不应与直流电压交叉连接；当这种情况发生时，峰值电压将超过MOV额定值并导致故障。由于大多数交流电源必须在中性点接地的情况下工作，所以会出现故障。
