The IS200ESELH1A is an advanced Exciter Selector Board used in GE EX2100 excitation systems, responsible for switching between redundant exciter controllers. This board plays a vital role in maintaining reliability and seamless operation in turbine generator systems, particularly within power plants and heavy industrial setups.

Engineered for high-performance applications, the IS200ESELH1A facilitates manual or automatic control transfers between redundant regulators (such as regulator A and B). This functionality is essential in maintaining system stability, reducing downtime, and supporting high-availability operations.

The board is mounted within the control cabinet of the EX2100 system and interfaces with other boards such as control processors and contact input boards. It accepts various digital inputs and outputs and uses onboard relays to execute switching logic. Thanks to its built-in diagnostics and self-monitoring features, the IS200ESELH1A helps engineers identify faults quickly and supports predictive maintenance protocols.

Whether you’re performing an upgrade, replacing a failed unit, or building a new excitation system, this Exciter Selector Board offers the assurance of long-term reliability and consistent performance.
