Woodward 9907-149 ProTech 203 De-energize-to-Trip Electronic Overspeed Protection System

Key Features

  • Triple - Channel Redundancy: Three fully independent speed - sensing units, each with its own power supply, MPU interface, and trip relay, ensuring no single - point failure disables protection.
  • 2 - out - of - 3 Voting Logic: Trip relay activation requires agreement from at least two units, balancing safety and avoiding false trips from a single faulty unit.
  • De - energize - to - Trip Safety: Default safety configuration where power loss triggers the trip relay, minimizing risk of failed trip during power outages.
  • On - line Maintainability: Modular design allows hot - swapping of a single failed unit without shutting down the prime mover, reducing downtime.
  • Real - time Monitoring & Diagnostics: Front - panel LCDs display speed from each MPU, the highest speed reading, and system status; LEDs indicate power, MPU health, and trip conditions.
  • Configurable Protection Parameters: Programmable overspeed setpoints, MPU fault timeouts, MPU fault setpoints, and gear tooth counts to match specific machinery requirements.
  • On - line Testing Capability: Supports overspeed test mode without triggering actual turbine trips, enabling verification of system functionality during operation.

Woodward 9907-164 505 Digital Governor Controller

Key Features

  • Precision Speed Regulation: Maintains ±0.1% steady-state speed accuracy across load changes to ensure stable turbine/generator output.
  • Split-Range Actuator Support: Drives 1–2 steam inlet valves via dual actuator outputs for single or split-stage steam admission control.
  • Integrated Operator Control Panel: 2-line LED display + 30-key keypad enables local parameter setup, status monitoring, and overspeed test initiation.
  • Critical Speed Avoidance: Automatically skips user-defined critical speed bands during startup/shutdown to prevent turbine resonance damage.
  • First-Out Trip Indication: Logs and displays the root cause of shutdowns (overspeed, low oil pressure, high temperature) for rapid troubleshooting.
  • Modbus Communication: RS-232/RS-422 ports support remote configuration, data logging, and SCADA integration via 505View software.
  • Auto Start/Stop Sequencing: Executes preprogrammed start/stop logic with warm-up delays and load ramp rates to optimize turbine life.
  • IP56 Enclosure: Protects against dust and water ingress for reliable operation in petrochemical/refinery environments.

Woodward E309-1583 ECL02

Key Features

  • Dual Load Sharing Modes: Supports isochronous (fixed frequency) and droop (proportional kW sharing) to match grid/isolated system requirements.
  • PWM Speed Reference Output: Delivers precise duty‑cycle signals to adjust engine speed controls for real‑time load balancing across paralleled gensets.
  • 3‑Phase PT/CT Sensing: Measures true RMS voltage/current to calculate real power (kW) with ±0.5% accuracy for precise load distribution.
  • Surge & Polarity Protection: Guards PT/CT inputs and power supply against transients and reverse wiring to prevent board damage.
  • UL/CE Compliance: Validated for global industrial use, including harsh environments in power generation and oil/gas sectors.
  • Plug‑and‑Play Integration: Direct replacement for ECL01 boards in 9907‑838 modules; no additional wiring for retrofits.
  • Broad Frequency Compatibility: Operates with 50–400 Hz gensets for marine, industrial, and emergency power applications.
  • Low Power Consumption: 5 W @ 25°C minimizes heat generation for extended component life in sealed enclosures.
