WOODWARD 8440-2251

الوصف

The Woodward 8440-2251 is a specific part number that identifies an easYgen-1400 controller. This is a small, but capable Automatic Mains Failure (AMF) controller from Woodward’s easYgen-1000 series, designed for single-generator set applications.

WOODWARD 8440-2251: easYgen-1400 AMF Genset Controller

The Woodward 8440-2251 easYgen-1400 is a key component in a generator set control system, offering advanced features for both standby and prime power applications with automatic changeover capabilities.

Product Overview

• Product Type: Automatic Mains Failure (AMF) Genset Controller
• Manufacturer: Woodward
• Series: easYgen-1000 Series (specifically the easYgen-1400 variant)
• Function: The easYgen-1400 is designed to automatically monitor the utility (mains) power supply, and in the event of a failure, it will automatically start the generator set, transfer the load to the generator, and then, upon restoration of mains power, seamlessly transfer the load back and shut down the generator. It also provides comprehensive control and protection for the generator set itself.
• Key Features:
  • Automatic Mains Failure (AMF) Function: This is a primary feature, enabling the controller to detect mains power outages and initiate the genset’s start-up and load transfer.
  • LCD Display: Features a large Liquid Crystal Display for clear local monitoring and configuration.
  • Configurable I/Os: Offers configurable inputs and outputs to connect various sensors, actuators, and interface with external systems.
  • Electronic Engine Support: Includes a CAN bus (J1939) interface for direct communication with electronic engine ECUs (Electronic Control Units). This allows for monitoring and control of critical engine parameters such as water temperature, oil pressure, speed, and fuel consumption for various engine manufacturers (e.g., Bosch, Cummins, John Deere, MTU, Perkins, Scania, Volvo, Woodward).
  • Comprehensive Protection: Provides extensive engine, generator, and utility (mains) protection functions, including over/under voltage, over/under frequency, loss of phase, reverse power, overcurrent, and more.
  • Power Metering: Capable of measuring and displaying 3-phase voltage, current, power parameters, and frequency for both generator and mains supply.
  • Communication Ports: Equipped with CAN J1939, RS-485, and USB for diagnostics, configuration, and remote communication.
  • Event Log and Real-Time Clock: Stores events and data with a real-time clock for diagnostics and troubleshooting.
  • Maintenance Scheduler: Includes features for tracking operating hours, starts, and scheduling maintenance activities.
  • Switchable Parameter Sets: Can store multiple parameter sets for different AC system windings, rated voltage, frequency, current, power, and speed, enhancing flexibility for various applications.
  • Configuration Flexibility: Can be configured from a computer via USB or directly from the front panel with password protection.
  • Manual Breaker Operation: Allows for manual control of circuit breakers via tactile buttons on the front panel.

Detailed Description

The easYgen-1400 (8440-2251) stands out within its series due to its integration of AMF functionality, making it ideal for critical standby power applications where automatic transfer between utility and generator is required. Its compact size, coupled with a robust feature set and electronic engine support, provides significant value for OEM genset packagers and system integrators.

It offers a more comprehensive control solution than the basic easYgen-400/600, adding mains monitoring and automatic transfer capabilities, while maintaining ease of setup and commission.

Applications

The Woodward 8440-2251 easYgen-1400 is commonly used in single-generator set applications requiring automatic mains failure and comprehensive control, such as:

• Critical Standby Power: Managing gensets that provide emergency backup power to commercial buildings, hospitals, data centers, and other facilities where uninterrupted power is crucial.
• Prime Power with Backup: In locations where utility power is unreliable or unavailable, it can manage the genset as the primary power source while still monitoring and reacting to any external power source.
• Rental Power: Flexible control for mobile generator sets that might be deployed in various standby or prime power scenarios.
• Pumping Units: Can also be applied to engine-driven pumping units for control and indication, with the option to inhibit relays if only monitoring and alarming are needed.

Obsolescence and Replacement Options

It’s important to be aware of the current status of the 8440-2251:

• Obsolescence: While the easYgen-1000 series, including the 8440-2251 (easYgen-1400), was a robust and widely used product line, it belongs to an older generation of Woodward controllers. As of today (July 31, 2025), newer and more advanced product lines have been introduced. This means direct sales and manufacturing of the 8440-2251 may be limited or discontinued due to component obsolescence.
• No Direct Substitute: There is typically no direct, one-for-one substitute with the exact same form factor and identical features for older, specific part numbers like the easYgen-1400.
• Recommended Replacements: Woodward continuously updates its product portfolio. The likely modern equivalents or next-generation controllers for similar single-genset AMF applications would be found within the easYgen-1000 series (newer variants) or the easYgen-3000XT series. These newer controllers generally offer:
  • Improved processing power and memory for more complex control algorithms.
  • Enhanced communication options, including more robust Ethernet capabilities and expanded USB functionality.
  • More advanced diagnostic and protection features.
  • Updated display interfaces and potentially more user-friendly configuration tools with modern software.
