Key Features

• Plug‑and‑Play Redundancy: Fully pre‑configured to match host system parameters; no re‑programming needed for hot swap. Automatically synchronizes speed data, trip setpoints, and alarm logic with primary modules.
• TMR Voting Logic Compatibility: Integrates into 2‑out‑of‑3 voting architecture to avoid false trips and ensure trip reliability if a primary module fails.
• On‑Line Maintainability: Hot‑swappable design allows replacement while the turbine is running, eliminating safety system downtime during module failure.
• Shared System Status: Exchanges real‑time speed, trip latch, and alarm status with all modules (A/B/C) for consistent monitoring and event logging.
• MPU & Speed Fault Handling: Supports MPU open‑wire/loss‑of‑speed detection and speed difference alarms to validate sensor health during operation.
• Event Logging & Diagnostics: Equipped with a real‑time clock for time‑stamped trip/alarm logs; synchronizes with other modules for consistent time‑averaging and post‑incident analysis.
• Sulfur‑Resistant Coating: Uses a conformal coating to protect against H₂S/SO₂ gases (IEC 721‑3‑3 Class 3C2), suitable for petrochemical/offshore environments.

Key Features

• Dual - Mode Operation: Runs in simplex for cost - effective small - scale systems or redundant mode for high - availability critical applications, with automatic failover in redundant setups.
• Integrated Data Storage: 64 MB flash memory retains firmware, application code, and event logs during power loss; 128 MB RAM enables fast program execution and real - time control loops.
• Real - Time Monitoring: The real - time clock timestamps all events (alarms, trips, mode changes) for post - incident analysis and compliance reporting.
• Hot - Swappable Redundancy: In redundant mode, the standby CPU automatically takes over within milliseconds if the primary CPU fails, with no process interruption.
• VMEbus Compatibility: The on - board FPGA provides VMEbus master/slave functionality to interface with all MicroNet I/O modules (discrete, analog, speed, temperature).
• Secure Configuration: The service port uses password - protected access to prevent unauthorized changes to control logic and parameters.
• Firmware Upgradability: Flash memory supports in - field firmware updates via the service port or Ethernet for feature enhancements and bug fixes.
• Hazardous Area Rating: CSA Class 1, Division 2 certification allows deployment in petrochemical, offshore, and other hazardous industrial environments.

Key Features

• Integrated Graphical HMI: 8.4‑inch color display enables real‑time trending, alarm visualization, and intuitive navigation; multilingual support simplifies global operation.
• Marine & Hazardous Compliance: ATEX Zone 2 and IACS UR E10 ratings allow deployment in offshore platforms, LNG carriers, and commercial marine vessels.
• Auto‑Start Sequencing: Configurable hot/cold start routines with temperature input integration to optimize start‑up time and turbine stress.
• Redundant Speed Sensing: Dual speed channels validate input integrity; zero‑speed detection and peak speed indication for overspeed trip confirmation.
• Critical Speed Avoidance: 3 programmable speed bands to bypass resonant frequencies and prevent turbine damage during acceleration/deceleration.
• Advanced Load Control: Remote droop, frequency dead‑band, and slip‑frequency synchronization for grid/load matching and stable parallel operation.
• Event Logging & Diagnostics: Real‑time clock (RTC)‑stamped trip/alarm logs; self‑diagnostics for I/O, speed sensors, and communication faults.
• Hot‑Swappable Configuration: Parameter changes and firmware updates via HMI or RemoteView without system shutdown.
