Product Overview
The Woodward 9907-1200 is a high-precision digital speed control module engineered for critical engine and turbine applications. As part of Woodward’s 9900 series, this device provides reliable speed governing, load sharing, and process control for gas turbines, diesel generators, and combined-cycle power plants. The Woodward 9907-1200 integrates advanced PID algorithms with dual-channel redundancy to ensure uninterrupted operation in mission-critical environments. Its modular design supports hot-swappable components, minimizing downtime during maintenance or upgrades.
Certified for ISO 8528-5 and API 670 standards, the Woodward 9907-1200 delivers ±0.25% steady-state speed regulation, making it ideal for grid synchronization and frequency stabilization. The controller’s robust communication suite includes Modbus TCP/IP, J1939 CANbus, and Woodward’s proprietary DSLC protocol, enabling seamless integration with SCADA systems and third-party PLCs. With an operating temperature range of -40°C to +85°C and MIL-STD-810G shock/vibration resistance, the Woodward 9907-1200 excels in harsh environments such as offshore drilling platforms and mobile power generation units.

Key Functional Features
The Woodward 9907-1200 combines adaptive control logic with industry-leading reliability. Its dual-processor architecture executes parallel control loops with continuous cross-verification, detecting and isolating faults within 10 ms. The module’s dynamic gain adjustment automatically compensates for load changes in reciprocating engines, preventing hunting and overspeed conditions.
Advanced operational capabilities:
- Isochronous/Droop Mode Switching: Enables seamless transition between islanded and grid-connected operations.
- Built-in HMI: 4.3-inch color touchscreen provides local parameter tuning, real-time trending, and event logging.
- Predictive Diagnostics: Monitors actuator health, battery backup status, and sensor drift, generating alerts via Syslog or email.
Application Scenarios
The Woodward 9907-1200 is pivotal in energy and industrial sectors. In gas turbine power plants, it governs fuel valve positioning to maintain ISO frequency during load transients. Data centers rely on its CANbus integration to synchronize backup generators with UPS systems during grid outages.
For marine applications, the Woodward 9907-1200 manages propulsion engine speed while interfacing with vessel automation systems via Modbus TCP. Oil & gas operators deploy it in compressor stations for anti-surge control, coordinating with Woodward SZR governors. Renewable energy systems utilize its droop compensation to balance photovoltaic/wind farms with diesel-hybrid microgrids.
