WOODWARD 8928-7555

الوصف

The Woodward 8928-7555 is a specific part number that identifies a KIT – LECM-MAIN KIT, R30 SERIES, WITH LECM ACCESSORIES. This is not an electronic control module itself, but rather an accessory kit that provides essential components and possibly the main module for a Large Engine Control Module (LECM) from the R30 series.

WOODWARD 8928-7555: LECM-MAIN KIT, R30 SERIES, WITH LECM ACCESSORIES

The Woodward 8928-7555 is a specialized kit manufactured by Woodward, designed to provide the core components and necessary accessories for implementing an LECM-based (Large Engine Control Module) control system. The key identifier here is its association with the R30 Series, which denotes a specific generation or type of LECM main control unit.

Product Overview

• Product Type: Kit for Large Engine Control Module (LECM)
• Manufacturer: Woodward
• Part Number: 8928-7555
• Series: R30 Series (referring to the LECM Main module included or intended)
• Function: This kit provides the primary components for a LECM-based engine control system. It typically includes:
  • LECM Main Module (R30 Series): The core electronic control unit that handles the primary processing and control algorithms for the engine.
  • LECM Accessories: Various supplementary components necessary for the installation, wiring, and general operation of the LECM. These might include:
    • Mating connectors/plugs for wiring harnesses.
    • Terminal pins for electrical connections.
    • Basic mounting hardware.
    • Sealing gaskets or O-rings for environmental protection.
    • Possibly basic documentation or software media.
• Purpose: To provide a comprehensive package for deploying a standard LECM R30 series control system, simplifying procurement and ensuring compatibility of components.

Detailed Description

The 8928-7555 kit represents a packaged solution for integrating an R30 Series LECM into a large industrial engine application. LECMs are highly sophisticated electronic control units designed to manage all critical parameters of large internal combustion engines, including speed, load, air/fuel ratio (for gas engines), ignition timing, fuel injection, and protection functions.

Key characteristics of an LECM from the R30 Series and its associated kit:

• Integrated Control Capability: The LECM Main module acts as the brain of the engine control system, integrating various sensor inputs and driving actuators to optimize engine performance, efficiency, and emissions.
• Robust Design: Like all Woodward industrial controls, the LECM (and its accessories) would be designed to withstand harsh operating environments, including high temperatures, vibrations, and electromagnetic interference.
• Communication Interfaces: LECMs typically support standard industrial communication protocols such as CAN (J1939), Ethernet (Modbus TCP/IP), and Modbus RTU, allowing for seamless integration into larger plant control systems, remote monitoring, and diagnostic capabilities.
• Accessories for Ease of Use: The “with LECM accessories” part of the kit ensures that essential wiring and mounting components are provided, facilitating proper installation and connection to the engine’s various subsystems.

Applications

The Woodward 8928-7555 kit would have been used in various applications involving large reciprocating engines where precise and reliable electronic control is essential:

• Power Generation: For engine-driven generator sets (gensets) in base-load, standby, peak-shaving, and paralleling applications.
• Oil & Gas: For engines driving compressors, pumps, or drilling equipment in pipeline operations, refineries, or extraction sites.
• Industrial Prime Movers: In other heavy industrial processes where large diesel, natural gas, or dual-fuel engines serve as prime movers.
• Marine Applications: For engines used in marine propulsion or auxiliary power generation systems on vessels or offshore platforms.

Obsolescence and Replacement Options

It’s crucial to note the current status of the 8928-7555:

• Obsolescence (End-of-Life): The 8928-7555, associated with the R30 Series LECM (which falls under the broader, older LECM product lines, like the 723, 723+, and 828 series), has been officially inactivated (End-of-Life) by Woodward. This means direct sales and new production of this kit are discontinued due to component obsolescence. As of July 2025, any limited repair support that might have been available for related products is highly restricted or unavailable due to parts scarcity.
• Replacement: For new installations or replacements where this kit was previously used, you would need to consult with Woodward or an authorized distributor. Woodward has introduced newer, more advanced generations of LECM and general engine control platforms. The recommended replacements typically include:
  • Newer LECM SA (Stand-Alone) variants: Modern LECM SA main modules often paired with separate I/O expansion modules, offering enhanced capabilities, updated technology, and improved connectivity.
  • Flex500 Series: A highly flexible and modern control platform that can support extensive I/O and custom control logic for a wide range of complex engine applications.
  • 2300E Series: Another powerful electronic control option suitable for sophisticated engine management and diagnostics.
