Woodward 8440-1947 E easYgen-3500-5 Generator Paralleling Controller

Product Description: The 8440-1947 E is Woodward easYgen-3500-5 genset power management controller, belonging to the legacy easYgen‑3000 series. It is designed for generator paralleling, mains tie-breaker control and island microgrid applications. Revision “E” stands for hardware and firmware revision, which defines the built-in protection algorithms, communication stack and grid compliance settings. It supports multi-generator synchronous paralleling, active and reactive load sharing, comprehensive generator protection, engine control and programmable LogicsManager logic.

Features:

• Full-featured paralleling controller for generator synchronizing, load sharing and bus tie control
• Integrated engine start/stop sequence, voltage & frequency regulation, generator and engine protection
• LogicsManager programmable logic function, flexible for custom interlock and alarm logic
• Communication interfaces: Modbus RTU, CANopen, peer-to-peer bus for multi-unit parallel network
• Local color LCD display and keypad for parameter setup, real-time measurement, alarm and event log
• Wide DC supply voltage range, suitable for diesel/gas engine battery power supply in power stations
• Revision E firmware optimized for marine, industrial backup power and microgrid grid codes
• Supports multi-breaker configuration, bus sectionalizing and mains import/export control

Applications:

• Industrial standby generator parallel system
• Marine vessel genset and switchboard control cabinet
• Data center, hospital critical emergency power system
• Oil & gas on-site distributed power generation
• CHP cogeneration plant and off-grid microgrid control

FAQ:

Q: What is the difference between 8440-1947 E and 8440-1934 E?
A: Both are easYgen-3500-5, different part numbers correspond to different factory pre-configured I/O and firmware packages. They are not directly interchangeable without parameter backup and firmware matching.

Q: Can I replace revision E with other revisions?
A: Revision letter is critical. Different revisions have different hardware components and firmware versions; direct plug-and-play replacement is not recommended.

Q: Is 8440-1947 still in production?
A: This is an obsolete legacy model. Available stock is NOS surplus or refurbished units.
