Woodward 8440-1934 E easYgen-3500-5 Generator Controller

Product Description: The 8440-1934 E is Woodward easYgen-3500-5 genset paralleling controller, part of the easYgen‑3000 series power management control platform. It integrates generator automatic start/stop, voltage and frequency regulation, synchronizing, load sharing, generator protection and programmable logic control. The revision letter “E” indicates hardware and firmware iteration, which affects function configuration and compatibility. It supports peer‑to‑peer parallel operation for multiple generators and utility tie‑breaker control for islanded and grid‑connected power systems.

Features:

• Full‑function genset control: auto start/stop, sync, load sharing, overcurrent, over/under voltage, over/under frequency protection
• Built‑in LogicsManager programmable logic, reduces extra PLC requirements
• Supports CANopen, Modbus RTU, peer communication bus for multi‑unit paralleling
• Color local display, keypad for onsite parameter setting, alarm and event log recording
• Wide DC power supply range, suitable for engine battery power supply in power station cabinet
• Supports up to 32 generators parallel operation, complex bus segmentation and utility tie control
• Revision E version with updated firmware for grid code and marine application optimization

Applications:

• Industrial backup power generator sets
• Data center and hospital emergency power system
• Marine vessel generator parallel control cabinet
• Oil & gas site distributed power generation
• CHP cogeneration and island microgrid control

FAQ:

Q: What does revision E mean for 8440-1934?
A: The suffix E is hardware/firmware revision; different revisions are not fully plug-and-play compatible, the parameter file and firmware version must match.

Q: What is the difference between easYgen-3500-5 and other easYgen models?
A: easYgen‑3500 series targets complex paralleling, multi‑breaker and utility tie control, higher function level than 3100/3200 versions.

Q: Is 8440-1934 still in production?
A: This legacy easYgen-3500-5 controller has been phased out; available stock is surplus new old stock or refurbished units.
