GE IS215UCVEM09B Mark VI LCI VME Controller Card

Technical Specifications

Function Features

• LCI – Optimized Control Processing: Executes Mark VI LCI control algorithms for load commutated inverter operation, turbine speed regulation, and LM aero – derivative turbine load management with deterministic performance.
• High – Speed I/O Processing: Interfaces with Mark VI I/O modules to collect and process sensor data (temperature, pressure, vibration) and send command outputs to actuators and LCI subsystems.
• Dual Ethernet Communication: Supports real – time data exchange with operator stations, DCS, and remote monitoring systems, enabling centralized control and monitoring.
• Redundant Power Inputs: Dual 24 VDC power sources guarantee continuous operation even if one power supply fails.
• VME64 Bus Integration: Facilitates communication with Mark VI I/O, safety controllers, and communication boards for modular system expansion and flexible configuration.
• Conformal Coating: Shields against moisture, dust, and chemical contaminants commonly found in turbine enclosures and power plant environments.
• Deterministic Clock Synchronization: Synchronizes with the VCMI communication board clock within ±100 microseconds via an external clock interrupt for precise control timing.
• Hot – Swappable Design: Edge connectors allow for module replacement without system shutdown, minimizing downtime during maintenance.
• Diagnostic Monitoring: Features status indicators for power, communication, and fault conditions, and is compatible with GE ToolboxST software for remote diagnostics, firmware updates, and control logic verification.

Application Scenarios

• LM Aero – derivative Turbine Control: Acts as the primary controller for Mark VI – based LM aero – derivative turbines, managing speed, combustion, and LCI – specific functions for marine and land – based power generation.
• LCI (Load Commutated Inverter) Systems: Controls LCI operation in turbine – generator sets, ensuring smooth power conversion and grid synchronization.
• Steam/Gas Turbine Retrofits: Serves as a direct replacement for legacy controller modules in Mark VI system upgrades, enhancing processing power and LCI control capabilities.
• Combined Cycle Power Plants: Integrates with gas and steam turbine subsystems to optimize combined cycle operation, load distribution, and grid stability.
• Industrial Power Generation: Operates reliably in harsh environments with protection against vibration, temperature fluctuations, and electromagnetic interference, suitable for refineries, petrochemical plants, and independent power producers.
• Marine Turbine Control: Tailored for marine – specific LM turbine applications, managing propulsion and power generation systems with robust communication and control features.

Compatibility and Integration

• Mark VI Ecosystem: Fully compatible with Mark VI I/O modules (such as IS210AEAAH2B, IS210AEDBH4AGD), safety controllers (like IS215UCCCS05A), and VCMI communication boards for seamless system integration.
• Software Support: Configurable and monitorable using GE ToolboxST software, which offers tools for control logic programming, LCI parameter tuning, data logging, and diagnostic analysis.
• VCMI Clock Synchronization: Integrates with the VCMI communication board to maintain precise system timing across distributed Mark VI components.
• Sensor/Actuator Compatibility: Interfaces with temperature transmitters, pressure sensors, vibration transducers, and LCI – specific actuators for comprehensive turbine monitoring and control.
• Documentation: Detailed guidelines can be found in the GE Speedtronic Mark VI System Manual (GEH – 6421H) and UCVE Controller Application Guide.
