IS200EXHSG3A – Exciter High Speed Relay Driver Board

The IS200EXHSG3A is a High-Speed Relay Driver Board designed by General Electric (GE) for use in the GE EX2100 Excitation Control System. As part of the EX2100 platform, this board plays a crucial role in enabling rapid relay operations required for generator protection and control. It is specifically engineered to deliver high-speed signal processing and actuation of external relays, ensuring the fast response needed in critical turbine-generator applications.

This board is responsible for driving protective relay outputs that initiate key functions such as field flashing, field breaker operations, or emergency field shutdowns. The IS200EXHSG3A interfaces with the EX2100 controller and other excitation components to receive commands and convert them into precise, time-sensitive relay outputs. The speed and reliability of this board are essential for protecting both the exciter and the connected synchronous generator from overvoltage, overcurrent, or system faults.

Equipped with multiple relay channels, the IS200EXHSG3A supports optically isolated inputs and outputs, ensuring safe electrical separation between the logic-level control circuits and the high-power switching functions. This insulation minimizes noise, cross-talk, and potential damage due to transient voltages or ground faults.

The board is built with rugged components that withstand extreme thermal, electrical, and mechanical conditions typically encountered in turbine control environments. Its conformal coating, precise layout, and compliance with GE’s industrial environments standards make it a dependable component in power plants and generator excitation systems worldwide. Additionally, the board supports remote monitoring and diagnostics, enhancing system uptime and reducing the need for manual maintenance.

Designed to operate in harsh industrial environments, the board features robust componentry, conformal coating, and compliance with GE’s strict quality standards for power generation applications. Its integration within the EX2100 system allows for deterministic timing, event logging, and remote diagnostics, contributing to more reliable generator control systems and reduced downtime.
