Key Features and Advantages

The **8290-191** provides precision speed regulation for gas/diesel engines and turbines. Its adaptive PID control algorithm dynamically adjusts to load changes, maintaining ±0.1% stability under transient conditions. Dual redundant processors with failover logic ensure continuous operation, while integrated surge protection (IEC 61000-4-5) safeguards against voltage spikes. The module supports isochronous/droop modes and load-sharing via CANbus for multi-engine synchronization.

Woodward’s **Toolkit™** software enables graphical configuration of response curves and fault diagnostics. The cast aluminum housing with conductive coating resists EMI/RFI interference, critical in power generation environments. Built-in data logging stores 1,000+ runtime events for failure analysis. Optional SAE J1939 compliance simplifies integration with mobile equipment.

Application Areas

Prime power generation for backup generators, marine propulsion engine control, and gas compressor stations. Used in CHP (Combined Heat & Power) systems for frequency regulation and in oilfield drilling rigs for hydraulic pump speed management. Also deployed in renewable energy hybrids to balance diesel/battery loads.

Installation and Maintenance

**Installation**: Mount vertically using M6 bolts to minimize vibration transfer. Shield all signal cables and maintain 50 cm separation from high-current lines. Use Woodward-approved **Cable Kit 8270-100** for CANbus connections. Ground the chassis directly to the engine block (≤0.1 Ω resistance).

**Maintenance**: Perform annual calibration with NIST-traceable RPM source. Replace the lithium backup battery (CR2450) every 5 years to retain configuration data. Clean air vents quarterly using low-pressure compressed air. Update firmware via isolated USB interface only.

Product Assurance

Woodward’s **8290-191** undergoes 1,000-hour accelerated life testing with thermal cycling (-40°C to +125°C). The 5-year warranty covers all electronic components, with 24/7 global technical support. Compliance with ISO 8528-5 for genset transient response ensures grid-code compatibility. Full documentation includes SIL 2 safety case reports for critical installations.

Note: Specifications subject to change. Confirm configuration with Woodward’s configurator tool (PN: 8270-500) prior to ordering.
