Product Description

The GE Excitation Control Board DS200EXDEG1A features 2 34-pin connectors, 2 10-pin connectors, and 5 indicator LEDs. It is also populated with 8 capacitors, test points, and terminal connectors.

The GE Excitation Control Board DS200EXDEG1A also is populated with multiple heatsinks. The heatsinks help cool heat-generating components on the board and without the heatsinks the components might be damaged. Or, the high heat might lead to premature failure. The heat sinks require 4 inches of space above the heatsinks for air flow to draw heat away from the heatsinks. This limits the positions in the drive interior where the board can be installed. It is best practice to first note where the old board is installed and install the replacement board in the same location.

To remove the old board, care is required to perform the task safely due to the weight of the board and the heatsinks that populate it.  Use one hand to remove the screws installed in each corner of the board. Use the other hand to support the board.

The board is also populated with LEDs that indicate the health of processing functions. If one or more LEDs are not lit, it indicates that an error has occurred or another problem has been encountered. To investigate further you can use the test points to test the specific circuits on the board. The test points each has an ID that is prefixed with TP and ends with a numerical value. TP1, TP3, and TP 6 are samples of test point IDs that you will encounter.
