IS200ERDDH1ABA 美国GE模块卡件 DCS系统备件

IS200ERDDH1A型号是EX2100系列的一部分，是励磁机调节器动态放电板。ERDD模型有两种操作模式，单工和冗余。每种应用模式的使用方式不同，安装方式也不同。

当IS200ERDDH1A用于单工模式时，该模型控制K3充电继电器；当板在冗余模式下使用时，它将控制K41灭磁继电器。在单工模式和冗余模式下运行时，ERDD模式的安装位置是不同的，在单工模式下，IS200ERDDH1A安装在ERBP背板中，在冗余模式下，必须使用两个ERDD型号，一个安装在与单工模式下的型号相同的位置，另一个板将安装在ERRB背板中。

该板的另一个功能是从电桥提供反馈，以观察输出场和DC链路电压。监控时，该板还允许观察输出分流电流、IGBT门驱动状态和电桥温度。IS200ERDDH1A板通常还用于通过模型的动态放电来控制过高的DC链路电压。

The IS200ERDDH1A model is part of the EX2100 series and is an exciter regulator dynamic discharge board. The ERDD model has two modes of operation, simplex and redundancy. Each application mode is used differently and installed differently.

When the IS200ERDDH1A is used in simplex mode, the model controls the K3 charging relay; When the board is used in redundancy mode, it will control the K41 field out relay. When running in simplex mode and redundancy mode, the ERDD mode is installed in a different location, in simplex mode, the IS200ERDDH1A is installed in the ERBP backplane, in redundancy mode, two ERDD models must be used, one installed in the same location as the model in simplex mode, and the other board will be installed in the ERRB backplane.

Another function of the board is to provide feedback from the bridge to observe the output field and DC link voltage. When monitoring, the board also allows observation of the output shunt current, IGBT gate drive status and bridge temperature. The IS200ERDDH1A board is also commonly used to control excessive DC link voltages through dynamic discharge of the model.
