Description
Of course. Here is a detailed product introduction and technical specification for the Woodward 9907-163 in English format:
Product Overview
Product Name: Analog Speed Control Module / Governor Controller
Model Number: 9907-163
Manufacturer: Woodward, Inc.
Series: 9900 Speed Controls
Primary Application: Engine and Turbine Speed Governing
The Woodward 9907-163 is a rugged analog speed control module designed for precise speed regulation of diesel engines, gas engines, and industrial turbines. It integrates with mechanical-hydraulic or electronic actuator systems to maintain stable rotational speed under varying load conditions. This module is widely used in power generation, marine propulsion, and industrial machinery where consistent speed control is critical for operational efficiency and safety.
Key Features
- Analog Speed Sensing: Accepts input from magnetic pickups (MPU) or tach generators for real-time speed feedback.
- Adjustable Speed Setting: User-configurable speed reference via potentiometer.
- Stability & Gain Control: Tunable stability circuits to prevent hunting and ensure smooth response.
- Droop Adjustment: Configurable droop (0–10%) for load-sharing in parallel generator applications.
- Robust Design: Industrial-grade construction with protection against vibration, temperature extremes, and electrical noise.
- Fail-Safe Operation: Includes overspeed protection and fault detection logic.
- Compatibility: Interfaces with Woodward actuators (e.g., UG, PGA series) and other third-party systems.

Typical Applications
- Power Generation:
- Governing standby/prime power diesel generators.
- Load-sharing in multi-generator paralleling systems.
- Marine:
- Main propulsion engine control for vessels.
- Auxiliary engine speed regulation.
- Industrial:
- Gas compressors and pumps in oil & gas facilities.
- Turbine-driven equipment in chemical plants.
- Emergency Systems:
- Fire pumps and mission-critical backup drives.
Configuration & Wiring
- Speed Input: Connect MPU (2-wire) to terminals
SPD+andSPD-. - Actuator Output: Wire to
OUT+andOUT-terminals (check polarity for direction). - Power Supply: 24V DC recommended (±10% tolerance).
- Reference Adjustment: Use onboard potentiometers for:
- Speed Setpoint (Idle/Rated RPM)
- Stability (damping)
- Droop (load-vs-speed slope)
Important Notes
⚠️ Safety Warnings:
- Only qualified personnel should install/service this device.
- De-energize power before wiring to avoid electrical hazards.
- Verify actuator compatibility to prevent mechanical overload.
🔧 Maintenance:
- Calibrate speed settings periodically using a calibrated tachometer.
- Inspect MPU alignment and air gaps (typically 0.5–1.0 mm).
- Replace faulty potentiometers if speed drift occurs.
📖 Documentation:
- Always refer to the Woodward Manual 82560 for installation, tuning, and safety guidelines.
- Use Woodward’s PSG Tuner software (if applicable) for advanced diagnostics.
Compatibility & Ordering
- Replacement Kits: Includes gaskets/mounting hardware (e.g., Kit Number 8276-1002).
- Cross-References: Compatible with legacy Woodward governors (e.g., 2301A systems).
- Spare Parts: Actuator cables (e.g., 9907-247), MPU sensors (e.g., 9907-901).
