Description
Product Overview
The IS200ESELH2AAA Exciter Selector Board from GE is a high-reliability control interface for EX2100 excitation systems. It receives six logic-level gate pulse signals from the IS200EMIOH1ACA master I/O board and distributes them to exciter gate pulse amplifier boards (EGPA) in the power conversion cabinet.

Control Logic & Redundancy
The IS200ESELH2AAA supports triple bridge control, making it suitable for systems requiring enhanced redundancy. It operates under the supervision of controller C, which selects either M1 or M2 as the active master. The board ensures reliable fanout of gate commands, isolating faults to prevent cascading failures.
Signal Distribution & Feedback
This board routes six gate signals to IS200EHPAG1ACB amplifier boards and provides feedback on master selection status. It ensures only one master drives the outputs at any time, maintaining system integrity and preventing signal overlap.
Application & Compatibility
The IS200ESELH2AAA integrates with GE EX2100 excitation systems and supports simplex or redundant configurations. It is ideal for turbine control environments requiring fault-tolerant gate signal distribution and real-time master switching.
