GE IS200EDISG1A励磁控制配电（EDIS）组件是一种用于控制和监视发电机的设备。它主要用于发电机的灭磁过程，在发电机出现异常或需要停机时，控制板会启动灭磁过程，以确保发电机安全停机。

灭磁控制板通过连接到EMIO和EXTB板来正常工作，当需要为EDEX板供电和控制时，EXTB板会进行操作。特别是在灭磁时，EXTB板会控制电流的流向，从而完成灭磁过程。但如果EXTB控制失败，EDEX模型可以启动灭磁。

在涉及到IS200EDEXG1B型的电源时，VDC将被发送到灭磁模块以对其供电

It is a device used to control and monitor generators. It is mainly used for the deexcitation process of the generator. When the generator encounters abnormalities or needs to be shut down, the control board will initiate the deexcitation process to ensure safe shutdown of the generator.

The deexcitation control board operates normally by connecting to the EMIO and EXTB boards. When it is necessary to power and control the EDEX board, the EXTB board will operate. Especially during demagnetization, the EXTB board controls the flow of current to complete the demagnetization process. But if EXTB control fails, the EDEX model can initiate demagnetization.

When it comes to the IS200EDEXG1B type power supply, the VDC will be sent to the deexcitation module to supply it with power
