IS200ESELH2A GE General Electric Exciter Selector Board DP Communication Board
Description:
The Exciter Selection Board IS200ESELH2A is a Group 2 ESEL model that operates with three bridge drivers. This board is used with the EMIO and EGPA boards to help fire up to six SCRs.
With this IS200ESELH2A it is the second group of the ESEL boards, as the second group to operate properly it contains three bridge drivers.
When being used in connection with the EGPA boards and if there are redundant controllers within the power conversion cabinet then two ESEL boards will need to be used, one will be powered by the M1 and the other by M2, the most active ESEL which is selected by controller C will send all of the necessary signals to the attached EGPA boards.
On the board, there are no jumpers or testpoints. P1 and P2 connect to the VME backplane and are not defined in this document because individual pin signals are not typically checked during troubleshooting. The following diagram depicts the layout of the ESEL board. Three green LEDs at the top of the front panel display the following status information:

Additional Information:
Features | |
Operation | Six gating commands are directed by the selectors from either M1 or M2 under the control of C. The active master provides all of the power required to command the six EGPAs. |
Failure of C | When C loses control power, M1 becomes the active master. |
Status Feedback | The ESEL informs its master which of the two masters has been selected as active. |
Reliable Fanout | Final output accurately fans out all six commands from either M1 or M2, but never both at the same time. If one of the fanout circuits fails, the other fanout circuits are unaffected. |
