Woodward 8440-2046 easYgen-3500-1-P1 Marine Module

Product Overview

The 8440-2046 (model designation: easYgen-3500-1 / P1-MARINE) is a flush-mounted marine generator controller produced by Woodward Inc. as part of the easYgen-3000 series. Designed for demanding marine and emergency power applications, it features a sealed soft-key interface with a large back-lit LCD screen, Class 0.5 measurement accuracy, and support for up to 10 display languages. Certified by major marine class societies including DNV, GL, BV, LR, and ABS, the module incorporates an internal LogicsManager to execute complex logic tasks. Weighing approximately 1.85 kg, it operates across wide temperature ranges (-40°C to +70°C) and supports setting current ranges from 1 to 32,000 A.

Core Technical Advantages

• Marine Class Approved Design: Fully certified by DNV, GL, BV, LR, and ABS for marine vessel power management and emergency gensets.
• Flush-Mount User Interface: Equipped with a sealed soft-key front panel and back-lit LCD display for direct manual operation in marine environments.
• Advanced LogicsManager Execution: Integrated programmable logic links input signals, internal states, and timers to perform complex control sequences.

Technical Specifications

Industrial Applications

• Marine Vessel Power Systems: Serves as a load sharing and synchronizing module in main and auxiliary vessel diesel generators.
• Emergency Power Gensets: Manages automatic starting, synchronization, and emergency breaker control on marine rigs and ships.
• Power Management System (PMS): Communicates via single-line bus topologies with up to 16 LS-5 circuit breaker controllers.

Wiring & Installation

• Flush Panel Mounting: Insert the controller into the control panel cutout and secure with flush mounting brackets to preserve panel sealing.
• Breaker Feedback Connection: Wire redundant dual generator breaker feedback signals to ensure fault-tolerant state monitoring.
• PMS Bus Integration: Connect the dedicated communication link between the generator unit and the central Power Management System (PMS).

Engineering Advantages

• Extreme Environmental Operating Range: Performs reliably in harsh marine ambient temperatures from -40°C to +70°C.
• Redundant Breaker Safety: Dual feedback tracking minimizes false breaker state readings during load transfer operations.
• Modular PMS Capability: Interoperates seamlessly with Woodward LS-5 controllers for multi-breaker distribution networks.
