WOODWARD 8270-1036 Product Introduction
1. Product Overview
The WOODWARD 8270-1036 is a high-reliability industrial speed controller engineered for precise regulation of engines, turbines, and other rotating machinery. It serves power generation, marine, oil & gas, and heavy-duty transportation industries—focusing on applications like diesel engine speed control, gas turbine load balancing, and generator frequency stabilization, which are critical for maintaining equipment efficiency and operational safety.
Integrating advanced control algorithms and robust input/output interfaces, it adapts to dynamic load changes while withstanding harsh industrial conditions. Compatibility with standard sensors (speed pickups, pressure transducers) and communication protocols ensures seamless integration into existing power systems, making it a trusted choice for demanding speed control tasks.

3. Product Specifications & Features
3.1 Core Specifications
The WOODWARD 8270-1036 is optimized for wide-range speed control (0–10,000 RPM), fitting both low-speed diesel engines (e.g., marine propulsion) and high-speed gas turbines (e.g., power generation). Its ±0.1% setpoint accuracy ensures stable engine/turbine operation, preventing frequency fluctuations in generators or speed deviations in production machinery.
Dual speed pickup inputs (magnetic/optical) enhance reliability—switching to the backup input if the primary fails. The PWM output directly controls fuel actuators, while load sharing mode enables synchronized operation of multiple engines (e.g., in parallel generator sets), balancing power distribution and reducing wear.
3.2 Key Features
- Dual Speed Inputs: Redundant speed pickups improve system reliability, critical for safety-critical applications (e.g., marine propulsion).
- Flexible Control Modes: Speed regulation, load sharing, and droop control adapt to diverse scenarios (e.g., standalone generators vs. parallel grid connection).
- Harsh Environment Resilience: IP65 enclosure and -40°C to +70°C operating range handle extreme temperatures, dust, and water splashes (e.g., offshore oil rigs).
- Marine-Grade Compliance: ABS certification makes it suitable for marine engines, meeting strict maritime safety standards.
- Easy Configuration: Modbus RTU communication enables remote parameter setting (e.g., speed setpoint, droop percentage), reducing on-site maintenance time.
4. Other WOODWARD Speed Control Products
Woodward offers complementary controllers for varied rotating machinery needs:
- WOODWARD 8270-1037: Variant with 4–20 mA speed reference (instead of 0–10 V), for industrial sensor compatibility (e.g., pressure-based speed adjustment).
- WOODWARD 8270-1040: High-power model (PWM output up to 2A) for large fuel actuators (e.g., heavy-duty diesel engines in mining trucks).
- WOODWARD 5460-376: Compact speed controller (0–5,000 RPM) for small engines (e.g., portable generators, lawnmowers).
- WOODWARD 2301A: Turbine-specific controller (for steam/gas turbines) with advanced temperature/pressure compensation.
- WOODWARD MPC-200: Multi-purpose controller (speed + load control) for hybrid power systems (e.g., diesel-electric marine propulsion).
