Product Overview
The GE IS200LSGIH1A is a Static Starter Control Gating Interface PCB designed for the EX2100e excitation system. It serves as the critical link between the UCSB controller and the power conversion bridges, managing analog outputs (0-10 V) and other essential functions. Its primary role is to deliver instantaneous overcurrent protection independent of the controller, making it a vital safeguard for your excitation system.

Key Features & Benefits
-
Instantaneous Overcurrent Protection: The IS200LSGIH1A can open the 52SS protection relay during overcurrent events, removing input power from the bridges and shielding the system from damage.
-
Comprehensive Interface: Connects the UCSB controller to power conversion bridges, analog outputs, pretrigger contact input, and analog input cooling returns.
-
Efficient Power Distribution: Distributes 28 V DC throughout the control cabinet, powering the LSGI board, UCSB controller, LSTB board, and 8-port switch.
-
Signal Transfer: Passes ±24 VDC to the FCSA board, which powers the LEMs. Communication occurs via a copper wire attached to a 12-pin plug.
-
Data Reception: Receives SCR voltage information from the FHVA card via the FGPA (Trigger Pulse Amplifier), ensuring coordinated system operation.
-
Robust Design: Features two sections with four standoffs each for daughterboard connections, three vertical pin connectors with clips, and four Augat connectors housing integrated circuits.
Industry Applications
The GE IS200LSGIH1A is designed for use in excitation control systems for steam, gas, or hydro generators. It is particularly suited for:
-
Power Generation Plants: Provides reliable static starter control for synchronous motors and generators, ensuring precise speed regulation.
-
Industrial Drives: Works as part of a static, adjustable frequency drive system, controlling the speed of synchronous machines.
-
Retrofit Projects: Integrates into existing EX2100e systems to upgrade or replace older gating interface boards.
Installation & Setup Guidance
When installing the IS200LSGIH1A, ensure the board is mounted securely using the four standoffs on each section. Connect the vertical pin connectors with attached clips to maintain reliable connections. The Augat connectors house integrated circuits; handle the board with care to avoid damage. For detailed instructions, refer to the GEH-6373 Load Commutated Inverter User's Manual.
Maintenance & Reliability
Regular inspection of the IS200LSGIH1A is recommended to ensure all connectors remain secure and the board is free from dust or moisture. The board's robust design, including seismic certification for Zone 4, ensures reliable operation in demanding environments. By maintaining the board, you extend its service life and reduce downtime, maximizing your return on investment.
Selection Guide
Before purchasing the GE IS200LSGIH1A, verify compatibility with your EX2100e system and confirm the required daughterboards. The board is available in stock at PLC Source PRO, a trusted supplier of industrial automation parts. Ensure you have the GEH-6373 manual on hand for setup and troubleshooting.
