Advantages and Features

1. Precise and Responsive Control: WOODWARD 9907-1200 delivers exceptional speed control accuracy (±0.1%) and fast loop response time (< 10 ms), ensuring stable operation of engines/turbines even under sudden load changes—ideal for power generation applications where grid frequency stability is critical.
2. Rugged Industrial Design: With a wide operating temperature range (-40°C to +70°C) and robust vibration/shock resistance, WOODWARD 9907-1200 performs reliably in extreme environments, such as offshore platforms, desert power plants, and marine engine rooms.
3. Versatile Integration Capabilities: Support for multiple industrial communication protocols (Modbus TCP, Ethernet/IP, OPC UA) and IEC 61131-3 programming makes WOODWARD 9907-1200 compatible with both Woodward’s proprietary systems and third-party automation equipment, reducing integration complexity.
4. Comprehensive Safety Functions: Built-in over-speed, over-temperature, and over-load protection logic (SIL 2 certified) ensures equipment shutdown in hazardous conditions, minimizing the risk of catastrophic failures and ensuring compliance with industrial safety standards.

Application Cases in Industries

• Power Generation (Gas Turbine Plants): WOODWARD 9907-1200 is used in 50 MW gas turbine control systems to regulate speed (3000 RPM for 50 Hz grids) and fuel flow. The module processes signals from speed sensors (high-speed counter input) and exhaust temperature thermocouples (analog input), then adjusts fuel injectors via analog outputs to maintain stable power output; in case of over-speed (exceeding 110% rated speed), the module triggers an emergency shutdown to protect the turbine.
• Oil and Gas (Offshore Drilling Rigs): In offshore drilling rig engine control systems, WOODWARD 9907-1200 manages the speed and load of diesel engines powering drilling machinery. It integrates with pressure sensors (4–20 mA input) to adjust fuel supply based on drilling load demands, while communicating with the rig’s SCADA system via Ethernet/IP to provide real-time operational data.
• Marine (Ship Propulsion Systems): For large container ship propulsion engines, WOODWARD 9907-1200 controls engine speed and thrust, synchronizing with the ship’s navigation system via CANopen. The module’s load-sharing function ensures balanced power distribution between multiple engines, optimizing fuel efficiency and reducing emissions.
• Heavy-Duty Machinery (Mining Trucks): In 300-ton mining truck engine control systems, WOODWARD 9907-1200 regulates engine speed based on driver input and load conditions (measured via pressure sensors). Its rugged design withstands the high vibrations and dust of mining environments, ensuring uninterrupted operation during long shifts.

Comparison with Competitors

Selection Suggestions and Precautions

• Selection Suggestions: Ensure WOODWARD 9907-1200 matches your equipment type (engine/turbine model) and control requirements—verify the number of analog/digital I/O channels, communication protocol compatibility (e.g., OPC UA for SCADA integration), and safety certification (SIL 2 for safety-critical applications). For multi-unit parallel operation (e.g., multiple generators in a power plant), confirm the module’s load-sharing function meets your system’s synchronization needs.
• Precautions:
  1. Installation and configuration of WOODWARD 9907-1200 must be performed by Woodward-certified technicians. Incorrect wiring of sensors/actuators or misprogramming of control logic may lead to equipment malfunctions or safety hazards.
  2. Use shielded cables for analog signal connections (e.g., thermocouples, pressure sensors) to minimize electromagnetic interference—critical in environments with nearby high-voltage equipment or motors.
  3. Regularly back up the module’s configuration and logged data via Woodward ToolKit Pro. In case of a module failure, the backup ensures quick restoration of control logic without downtime.
  4. Inspect the module’s LED status indicators (power, communication, fault) daily. If a fault indicator illuminates, use the diagnostic function in ToolKit Pro to identify the issue (e.g., sensor disconnection, over-temperature) and resolve it promptly.
