Key Features

1. Primary Turbine Trip & Protection
   • Executes hardware-based primary trip logic for overspeed, flame failure, vibration, and electrical fault conditions.
   • Delivers 2-RPM sensitivity for zero-speed detection, ensuring accurate turbine stop verification.
   • Provides 3 dedicated trip outputs for emergency shutdown (ESD) actuation.
2. Redundant High-Speed Communication
   • Dual 100 Mbps Ethernet ports support network redundancy, eliminating single points of communication failure.
   • Enables real-time, deterministic data exchange with the Mark VIe controller and remote I/O racks.
3. Comprehensive Signal Conditioning & Monitoring
   • Integrates 8 flame detector inputs for continuous combustion monitoring in gas turbines.
   • Processes shaft voltage, current, and bus voltage signals for electrical system health monitoring.
   • High-accuracy signal conversion (±0.1%FS) ensures precise data acquisition.
4. Rugged Industrial Reliability
   • Conformal-coated PCB and ruggedized components withstand extreme temperatures, vibration, and electromagnetic interference (EMI).
   • Compact, modular design enables easy installation, hot-swap replacement, and maintenance.
5. Seamless Mark VIe System Integration
   • Native compatibility with GE Speedtronic Mark VIe/VIeS platforms supports auto-reconfiguration during module replacement.
   • Works in simplex or TMR architectures to match system redundancy requirements.

Application Scenarios
