Woodward 8440‑2089 easYgen‑3500XT‑P1 Genset Controller

The Woodward 8440‑2089 is the easYgen‑3500XT‑P1 genset paralleling controller for multi‑generator power‑management systems. It integrates engine‑governor control, generator‑protection functions, synchronisation and load‑sharing logic, supporting multiple gensets paralleling with mains or island‑mode operation for critical power‑supply applications.

This panel‑mount genset controller is equipped with graphic LCD HMI, Ethernet, CAN J1939 and multiple serial communication ports. It provides comprehensive generator protective‑relay functions including over‑current, over‑voltage, reverse‑power and loss‑of‑mains protection. Widely used as aftermarket spare for data‑centre, hospital and industrial‑plant genset‑control cabinet overhaul, loop debugging and system retrofitting projects.
