GE Electric | DS200PCCAG1ACB | Communication processor carrier component
Product Description:
The GE DS200PCCAG1ACB is a Communication Processor Carrier Assembly for the Speedtronic Mark V turbine control system. It functions as a high-speed communication hub, housing critical processor modules (PCCA & PCCB) that manage real-time data exchange between the turbine controller, I/O modules, HMI interfaces, and networked devices via proprietary fiber optic networks (PDH/UDH).

Key Features:
- Dual-Processor Architecture: Parallel processing for fault tolerance (PCCA/PCCB).
- Fiber Optic Networks: Electrically isolated PDH (Plant Data Highway) & UDH (Unit Data Highway).
- High Availability: Redundancy switching <100ms for uninterrupted turbine control.
- Real-Time Data Routing: Synchronizes data between CPU, I/O packs, HMIs, and historian.
- Diagnostics Capability: On-board LEDs and software tools for network health monitoring.
- Hot Swap Support: Processor cards replaceable under power (with precautions).
- Robust Construction: Vibration/shock-resistant for power plant environments.
Primary Function & Purpose:
The DS200PCCAG1ACB provides synchronized, fault-tolerant communication infrastructure for Mark V systems. It ensures deterministic data exchange between protection systems, control processors, and operator interfaces – critical for safe turbine startup, load control, and emergency shutdowns.
Typical Applications & Use Cases:
- Gas/Steam Turbine Control: Real-time coordination of fuel valves, governors, ignitors.
- Protection System Integration: Tripping logic communication (overspeed, vibration, temperature).
- Plant-Wide Monitoring: Data aggregation for SCADA/DCS systems via UDH.
- Redundant Control Paths: Maintaining synchronized operation of primary/backup controllers.
- Sequence of Events (SOE) Recording: Time-stamping critical alarms across the network.
Application Field:
Exclusively deployed in critical turbine control systems within:
- Power Generation: Combined-cycle plants (CCPP), peaker plants, cogeneration facilities.
- Oil & Gas: Compressor stations driven by industrial gas turbines.
- Marine Propulsion: Naval vessels with turbine propulsion systems.
