Features:
- Identifies the H3 selector configuration with six bridge drivers.
- Maintains separate command sources for M1 and M2 redundancy.
- Leaves firing-pulse amplification to the downstream EGPA boards.
The H3 suffix on IS200ESELH3A defines the largest ESEL bridge-driver arrangement.
In a redundant control, controller C determines whether the M1-fed or M2-fed selector path is effective.
Firing energy is added only after each selected logic signal reaches its assigned EGPA.
The General Electric IS200ESELH3A Exciter Selector Board is supplied by Apter Power with quotation and technical assistance.

Logic-Level Fanout
- Command Origin: Gate requests are received from the corresponding EMIO
- Board Function: ESEL selects and distributes the logic pulses
- Cable Fanout: Up to six cable sets leave the H3 board
- Destinations: Each set connects to its corresponding EGPA board
M1/M2 Source Choice
- Board Pair: A redundant control uses two ESEL boards
- First Source: Controller M1 drives one selector board
- Second Source: Controller M2 drives the other selector board
- Active Path: Controller C chooses which ESEL output is used
Selector Capacity Codes
- H1 Group: One bridge-driver path is provided
- H2 Group: Three bridge-driver paths are provided
- H3 Group: Six bridge-driver paths are provided
- Current Variant: IS200ESELH3A carries the H3 six-driver assignment
Control and Bridge Roles
- Logic Input: EMIO supplies low-level gate commands
- Selection Stage: ESEL determines the distributed command path
- Pulse Stage: EGPA converts each selected command into firing energy
- Bridge Stage: The resulting pulses operate the associated SCR gates
