    GE IS220PTURH1A Primary Turbine Trip I/O Pack
    Manufacturer: General Electric (GE Vernova)
    Model: IS220PTURH1A
    Type: PTUR Primary Trip I/O Pack
    System: Mark VIe Speedtronic Turbine Control
    Function: Turbine overspeed & primary trip protection
    1. Overview
    The GE IS220PTURH1A is a critical safety I/O pack for Mark VIe turbine control systems, dedicated to **primary overspeed and trip protection** for gas/steam turbines. It provides high-speed, reliable monitoring of turbine speed via magnetic pickup inputs and executes fast-acting trip commands to protect equipment during hazardous conditions (e.g., overspeed). It integrates dual Ethernet for redundant communication and supports TMR (Triple Modular Redundancy) for safety-critical applications in power generation, oil & gas, and petrochemical plants.
