GE IS200TPROH1BBB: Protective Termination Board

1. Core Function and Positioning

2. Key Specifications from Product Documentation

3. Functional Role

• Signal Transmission: Acts as a bridge between field sensors (e.g., speed probes, temperature sensors) and the VPRO, relaying real-time data critical for turbine protection.
• Protection Coordination: Works with VPRO to trigger emergency shutdowns or safeguards if overspeed, voltage irregularities, or temperature extremes are detected, preventing turbine damage.
• EMI Mitigation: Integrates components like MOVs to filter electromagnetic interference, ensuring signal integrity and preventing false triggers in sensitive protection circuits.

4. Application Scenarios

• Gas Turbine Protection: Exclusively used in GE Speedtronic Mark VI systems for gas turbines in power plants, refineries, and industrial facilities, safeguarding against catastrophic failures.
• Critical Infrastructure: Ensures compliance with safety standards in high-risk environments where turbine overspeed or voltage instability could lead to operational hazards.
