Technical Specifications & Selection Guide

Selection Tip: Choose the 9904-264 for analog-based paralleling applications with up to 8 gensets. For digital networking (Modbus/CAN), consider upgrading to the Woodward 2301D series.

Core Features & Technical Advantages

• Dual-Mode Governing: Operates as a standalone isochronous speed governor or as a load-sharing controller in multi-unit paralleled configurations — no additional hardware required.
• Robust Analog PI Control: Heavy-duty proportional-integral algorithm delivers stable, oscillation-free speed response under rapid load transients common in industrial environments.
• Field-Tunable Stability: Front-panel potentiometers allow on-site gain, stability, and droop adjustments without specialized tools or software — ideal for remote installations.
• Precision Load Balancing: Maintains ±2% load sharing accuracy across paralleled gensets, preventing thermal overload and extending engine service life.
• Broad Fuel Compatibility: Fuel-agnostic design supports diesel, natural gas, and dual-fuel engines equipped with electronic or hydraulic actuators.
• Legacy System Support: Direct retrofit replacement for aging 2301A Control Module installations — minimal rewiring, maximum uptime recovery.
• Proven MTBF: Solid-state construction with no moving parts; field-validated MTBF exceeding 100,000 hours across global installations.

Typical Application Scenarios

From the perspective of a Senior Engineer managing critical power infrastructure, the Woodward 9904-264 addresses real-world pain points across multiple heavy industries:

• ✅ Oil & Gas Platforms: Offshore drilling rigs and onshore compressor stations demand uninterrupted prime mover control. The 9904-264 governs engine speed under fluctuating compressor loads, preventing costly production shutdowns.
• Power Plants & Utility Backup: Hospitals, data centers, and utility substations rely on paralleled diesel gensets for N+1 redundancy. This module ensures balanced load distribution and seamless load transfer during grid outages.
• ✅ Marine Propulsion Systems: Commercial vessels require smooth speed transitions during maneuvering and port operations. The 9904-264’s droop mode prevents hunting and instability in main and auxiliary engine configurations.
• ✅ Industrial Cogeneration (CHP): Combined heat and power plants with variable thermal and electrical demands benefit from the module’s isochronous control, maintaining frequency stability as process loads shift.
• ✅ Rental & Mobile Power Units: Temporary power contractors value the plug-and-play compatibility of the 9904-264 with standard Woodward actuator wiring, enabling rapid deployment across diverse generator models.

Logistics & Professional Service

• ✅ 2-Day Express Shipping: In-stock units dispatched within 24 hours via DHL, FedEx, or UPS to destinations worldwide.

FAQ — Frequently Asked Questions

Q1: What is the price of the Woodward 9904-264, and do you offer volume discounts?
A: Pricing for the Woodward 9904-264 varies based on order quantity, delivery urgency, and current stock levels. We offer competitive tiered pricing for OEMs, EPC contractors, and MRO procurement teams. Submit a Request for Quotation (RFQ) via sale@ninermas.com and receive a formal quotation within 4 business hours. Volume orders of 5+ units qualify for preferential pricing and dedicated account management.

Q2: Is this unit 100% Original and Brand New, or refurbished?
A: Every Woodward 9904-264 we supply is 100% Original and Brand New — never refurbished, repaired, or remanufactured. Units are sourced from authorized Woodward distribution channels and stored in climate-controlled warehouses to preserve factory condition.

Q3: Can you provide the official Woodward 9904-264 Datasheet and technical documentation?
A: Yes. The official Woodward datasheet, installation manual, and wiring diagram for the 9904-264 are available upon request. Contact our technical team at sale@ninermas.com with your project details, and documentation will be provided within 1 business day.

Q4: What is the lead time if the unit is not in stock?
A: In-stock units ship within 24-48 hours. For out-of-stock scenarios, our global sourcing network typically secures the Woodward 9904-264 within 3-7 business days. Expedited sourcing is available for emergency shutdowns — contact us with your required delivery date.

Q5: Is the 9904-264 compatible with non-Woodward actuators?
A: The 9904-264 outputs a standard 0-200 mA signal compatible with most Woodward and third-party electronic actuators. Hydraulic actuator compatibility depends on the actuator’s input impedance. Our engineers can advise on interface requirements for your specific application.

Q6: Can this module be used in a PLC System or DCS integration?
A: While the 9904-264 is a standalone analog Control Module, it can interface with PLC System and DCS environments via 4-20 mA analog I/O. For native digital protocol integration (Modbus RTU, CAN bus), the Woodward 2301D series is recommended as an upgrade path.
