Woodward 5437-1119 ProTech‑GII Redundant Spare Module

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.
