The GE IS215UCCCH4A is a cPCI (Compact Peripheral Component Interconnect) Controller Card for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. It is a critical component that serves as the central processing unit (CPU) for the entire control system.
Key Features and Functionality
The IS215UCCCH4A is the “brain” of the Mark VIe system. Its main functions include:
- Control and Processing: The controller executes all the primary control algorithms for the turbine, including fuel scheduling, speed control, load regulation, and synchronization.
- cPCI Architecture: The controller is based on the cPCI (CompactPCI) bus architecture. This is a rugged, high-performance industrial bus that provides reliable communication between the controller and the various I/O packs and modules.
- Processing Speed: The ‘H4A’ suffix indicates a specific hardware revision, often with enhanced processing capability compared to earlier versions.
- Communication: The controller handles all communication within the system and with external systems, such as a plant’s Distributed Control System (DCS) or SCADA system.
- Redundancy: In a redundant Mark VIe system (such as TMR – Triple Modular Redundancy), multiple UCCCH4A controllers work in parallel with voting logic to provide exceptional fault tolerance and reliability.
