IS200EISBH1A – Exciter ISBus Board

The IS200EISBH1A is an Exciter ISBus Board developed by General Electric (GE) for use within the advanced GE EX2100 excitation control system. This board is an integral part of the internal communication infrastructure, serving as the primary interface for ISBus (Internal System Bus) data transmission between the various components of the excitation system. It plays a critical role in synchronizing real-time data, ensuring the control, protection, and monitoring modules work cohesively.

The IS200EISBH1A is engineered to support high-speed, reliable, and redundant communication paths, enabling robust data flow across the exciter’s intelligent modules. It allows coordination between regulators, protection modules, feedback boards, and other critical control units, ensuring precise voltage regulation, quick fault response, and smooth system operation. Its functionality is crucial in applications where high reliability and operational integrity are demanded, such as steam, gas, and hydro turbine generators.

This board typically mounts within the EX2100 rack and interfaces with various terminal boards and processor modules using standard connectors. The ISBus protocol it supports is tailored specifically for GE’s excitation systems, offering deterministic communication timing, error-checking mechanisms, and system-wide synchronization. These features ensure that even under heavy electrical loads or disturbances, the excitation system remains stable and responsive.

Constructed with durable industrial-grade components, the IS200EISBH1A is capable of withstanding challenging environmental conditions found in industrial environments and power plant settings. It provides EMI protection, thermal stability, and long operational life, reducing maintenance frequency and downtime.

Whether part of a simplex or redundant EX2100 configuration, this board ensures the integrity of inter-module communication, which is essential for safe generator startup, real-time voltage control, and protective functions.
