WOODWARD 8440-2250

الوصف

The Woodward 8440-2250 is a specific part number that identifies an easYgen-400 controller. This is a compact, automatic start/stop generator set controller designed for various single-unit power generation applications.

WOODWARD 8440-2250: easYgen-400 Genset Controller

The Woodward 8440-2250 easYgen-400 is a member of Woodward’s easYgen-100 series, a family of controls specifically developed for reliable and efficient management of single generator sets.

Product Overview

• Product Type: Generator Set Controller (Genset Controller) / Automatic Start/Stop Controller
• Manufacturer: Woodward
• Series: easYgen-100 Series (specifically the easYgen-400 variant)
• Function: The easYgen-400 is designed to automatically or manually start, stop, control, and protect a single generator set. It provides essential algorithms and logic for robust genset operation.
• Key Features:
  • Automatic Start/Stop: Can initiate or shut down the genset based on remote signals.
  • Large LCD Display: Features a clear Liquid Crystal Display for local monitoring and configuration.
  • Configurable I/Os: Offers programmable inputs and outputs to connect various sensors and actuators.
  • Electronic Engine Support: Includes an engine ECU (Electronic Control Unit) interface, typically via CAN bus (J1939), to communicate with electronic engines for monitoring and control of parameters like water temperature, oil pressure, speed, and fuel consumption.
  • Comprehensive Protection: Provides extensive engine and generator protection functions (e.g., over/under voltage, over/under frequency, overcurrent, loss of phase, reverse power).
  • Power Metering: Capable of measuring and displaying generator parameters such as 3-phase voltage, current, power, and frequency.
  • Event Log: Stores an event log with a real-time clock for diagnostics and troubleshooting.
  • Maintenance Scheduler: Includes features for tracking operating hours, starts, and scheduling maintenance.
  • Multiple Parameter Sets: Can store switchable parameter sets for different AC system windings, rated voltage, frequency, current, power, and speed, useful for mobile genset applications.
  • Configuration: Can be configured from a computer via USB or directly from the front panel with password protection.
  • Compact Design: Its compact size (e.g., 135 x 110 x 44 mm) allows for easy integration into control panels.

Detailed Description

The easYgen-400 (8440-2250) is part of a series that offers exceptional versatility and value for OEM genset packagers and system integrators. It streamlines the control of generator sets in various isolated operations. While it excels at basic auto start/stop and protection, it does not include Automatic Mains Failure (AMF) functionality or advanced paralleling capabilities; for those, higher models in the easYgen series (like easYgen-1400 or easYgen-3000 series) would be used.

Its ability to communicate with engine ECUs via CAN bus is a significant feature, allowing for more integrated and precise control over electronic engines. The user-friendly LCD and configurable I/Os make it adaptable to a wide array of single genset applications.

Applications

The Woodward 8440-2250 easYgen-400 is typically used in single-generator set applications that require automatic or manual start/stop control and comprehensive protection, such as:

• Isolated Standby Power: Gensets providing backup power for facilities in case of a grid outage (without automatic transfer switch logic built into the controller itself, but can interface with external ATS).
• Prime Power: Gensets operating as the sole power source in isolated locations.
• Rental Power: Flexible control for mobile generator sets.
• Pumping Units: As a control and indicating instrument for engine-driven pumps.

Obsolescence and Replacement Options

It is important to note the current status of the 8440-2250:

• Obsolescence: The easYgen-100 series, including the 8440-2250 (easYgen-400), is an older product line. While specific “End-of-Life” notifications for the 8440-2250 itself might not be as explicit as some other older Woodward products (like the 48-pin ECMs or GCP-3x series), it belongs to a generation that has likely been superseded by newer models with enhanced features and updated components. Support and availability for such models become increasingly limited over time.
• No Direct Substitute: Similar to other older product lines, there may not be a direct, one-for-one substitute with the exact same form factor and identical features for the easYgen-400.
• Recommended Replacements: Woodward continuously updates its product portfolio. The likely modern equivalents or next-generation controllers for single-genset applications would be found within the easYgen-300XT series or easYgen-1000 series (e.g., easYgen-1400/1600 models for AMF applications if needed). These newer controllers offer:
  • Improved processing power and memory.
  • Enhanced connectivity options (e.g., more robust Ethernet, USB ports).
  • More advanced control algorithms and diagnostic capabilities.
  • Updated display interfaces and potentially easier programming tools.
