Description

KJ2003X1-BA2: Product Overview
The EMERSON KJ2003X1-BA2 is a central processing unit (CPU) module for the Mark VI Speedtronic Turbine Control System. This controller serves as the computational brain for managing and protecting gas or steam turbines in critical power generation applications. It is responsible for executing high-speed control algorithms, complex sequencing logic for startup/shutdown operations, and critical protection functions to prevent equipment damage.
Installed in a Mark VI system rack, the module operates within a robust architecture designed for maximum availability. It performs real-time processing of data from various I/O modules (handling inputs like temperature, pressure, vibration, speed) and executes control calculations to manage final control elements such as fuel valves, inlet guide vanes, and actuators. The controller is engineered for mission-critical performance where system failure is not an option, supporting configurations from simplex to full Triple Modular Redundancy (TMR) for the highest fault tolerance.

Core Features & Customer Value
The primary value of the KJ2003X1-BA2 is its exceptional reliability and deterministic performance​ in protecting multi-million dollar turbine assets. For plant owners, this translates directly to prevented catastrophic failures​ and maximized turbine availability. The controller’s high-speed execution​ ensures rapid response to fault conditions, while its advanced control algorithms​ optimize turbine efficiency and emissions compliance.
The TMR capability​ is a critical feature, allowing three controllers to operate in parallel with a 2-out-of-3 voting logic. This architecture ensures continuous operation even if a single controller fails, providing the highest level of availability for critical power generation assets. For engineers, the familiar ToolboxST programming environment​ simplifies configuration, troubleshooting, and lifecycle management, reducing engineering costs and minimizing downtime.
Typical Applications
  • •
    Gas Turbine Control:​ Managing fuel, combustion, and acceleration/deceleration sequences in heavy-duty or aeroderivative gas turbines.
  • •
    Steam Turbine Control:​ Governing speed and load, managing valve sequences, and providing overspeed protection.
  • •
    Turbine Protection:​ Executing critical shutdown logic based on vibrations, temperatures, speed, and other parameters.
