Description

Product Description WOODWARD 9907-1365

Product Parameters WOODWARD 9907-1365

• Device Type: Controller for medium-power gas engines with adaptive regulation and comprehensive protection functions.
• Functional Parameters:
  • Speed regulation range: 1000–3000 rpm (configurable) — suitable for generators and industrial-purpose engines.
  • Regulation accuracy: ±0.3% of nominal speed — stability for systems with sensitive equipment (e.g., computers in shopping centers).
  • Operating modes: Automatic adaptation to gas quality, grid synchronization, manual control, gas pressure monitoring — flexibility for various scenarios.
  • Protection types: Overspeed (2 levels), low gas pressure, overheating (exhaust gas temperature), ignition system failure — protection against accidents and environmental standard violations.
  • Supported sensors: Gas pressure sensors (4–20 mA), K-type thermocouples, magnetic speed sensors (12–60 teeth), ignition sensors — comprehensive monitoring of engine status.
  • Supported protocols: Modbus RTU, Ethernet/IP — integration with PLCs and operator panels (e.g., Allen-Bradley PanelView).
• Electrical Parameters:
  • Power supply: 24 VDC (redundant) — protection against power loss in critical systems.
  • Current consumption: ≤150 mA — moderate energy usage.
  • Control outputs: 3 analog outputs 4–20 mA (gas supply regulation, throttle), 5 relay outputs (NC/NO, 5 A, 250 VAC) — control of valves, signal lamps.
• Mechanical Characteristics:
  • Housing material: Aluminum with anti-corrosive coating — resistance to aggressive gas components.
  • Protection class: IP20 — installation in gas equipment control cabinets.
  • Temperature range: -20°C – 65°C (operating); -40°C – 80°C (storage) — operation in moderate and cold climates.
  • Dimensions: 100 × 150 × 45 mm (width × depth × height) — compact design for installation in limited spaces.

Advantages and Features WOODWARD 9907-1365

• Adaptation to gas quality: WOODWARD 9907-1365 automatically adjusts gas supply when its composition changes (e.g., fluctuations in propane content in mixtures), maintaining engine stability and reducing fuel consumption by 4–6% compared to static controllers.
• Two-level overspeed protection: Independent verification of signals from different sensors ensures WOODWARD 9907-1365 shuts down the engine during critical overspeed, preventing equipment damage.
• Flexible integration: Support for popular protocols allows WOODWARD 9907-1365 to be implemented in existing systems without replacing core equipment, reducing setup time.
• Resistance to aggressive environments: The anti-corrosive housing protects the controller from toxic gas components (e.g., hydrogen sulfide), extending service life by 1.5 times compared to standard models.

Application Cases in Fields

• Gas power stations for commercial facilities:
  • Controlling generators in shopping centers and office complexes: WOODWARD 9907-1365 ensures stable power supply, synchronizes with the grid, and protects against overloads during peak hours (e.g., opening times).
• Industrial heating systems:
  • Regulating engines of gas pumps and compressors: The controller optimizes gas supply, reducing consumption under partial loads and preventing overheating in high-intensity heating zones.
• Automotive gas stations:
  • Managing compressor engines for vehicle refueling: WOODWARD 9907-1365 stabilizes gas pressure in the system, ensuring safe and accurate refueling.

Comparison with Competing Products

• Better adaptation to gas quality: Automatic adjustment within 3–5 seconds vs. 10–15 seconds in competitors — faster response to fuel composition changes.
• More protection features: Two-level overspeed protection and ignition status monitoring, absent in some alternatives — enhanced reliability.
• Wider temperature range: Operation down to -20°C vs. -10°C in competitors — suitability for northern regions.

Selection Suggestions and Precautions

• Selection: Recommended for gas engines with 30–300 kW capacity in commercial, industrial, and energy facilities. Fully compatible with Caterpillar G3300, Cummins CG Series, and Kubota GX engines.
• Precautions:
  • For WOODWARD 9907-1365, regularly calibrate gas pressure sensors (every 6 months) — inaccurate data will lead to suboptimal regulation and increased consumption.
  • Use only certified gas filtration systems — contaminants can damage sensors and the controller.
  • Update firmware via Woodward GasPro software — new versions include adaptive algorithm improvements for new gas types.
  • Mount the controller at least 1 meter from electromagnetic interference sources (transformers, power cables) — ensuring stable sensor signals.
