Woodward 8440‑2088 (easYgen‑3500XT‑P2) Generator Paralleling & Power‑Management Controller
Product Brand & Model Title
Official Product Name: easYgen‑3500XT‑P2 Generator Paralleling & Power‑Management Controller Brand: Woodward Model No: 8440‑2088 Product Grade: Advanced genset synchronizing & load‑sharing controller for combined‑heat‑and‑power (CHP / Co‑Gen) applications; active production, available as new‑stock & spare‑part supply
General Product Overview
The 8440‑2088 is a panel‑mount genset control unit within Woodward easYgen‑3000 series, designated easYgen‑3500XT‑P2. It performs generator start‑stop logic, automatic synchronisation, load‑sharing, mains‑genset paralleling, comprehensive electrical protection and CHP / co‑generation functions. It supports three‑phase busbar voltage measurement and phase‑rotation supervision between utility bus and generator bus. Equipped with graphical LCD display and membrane soft‑keys, it supports expansion via IKD remote I/O modules, CANbus and Ethernet communication. Widely used for standby generators, prime‑power sets, combined‑heat‑power plants, industrial multi‑gen‑set paralleling systems and cogeneration installations。

Core Product Features
- Multi‑genset automatic synchronisation & load‑sharing: Paralleling between multiple generators and also generator‑utility mains tie‑breaker control.
- CHP / Co‑Gen dedicated functionality: Heat‑and‑power co‑generation control logic for combined‑heat‑power installations (P2 variant exclusive feature).
- Three‑phase bus‑voltage & phase‑rotation supervision: Monitors phase‑sequence matching between utility‑side bus and generator‑side bus to prevent wrong‑phase closing faults.
- Comprehensive generator‑protection functions: Over‑current, overload, over‑voltage / under‑voltage, over‑frequency / under‑frequency, reverse‑power protection.
- Graphical local HMI: Onboard LCD display, alarm‑event logging, real‑time electrical‑value viewing, parameter modification onsite.
- Remote I/O expandable architecture: CANbus connects IKD‑series DI/DO expansion modules for larger‑scale I/O demands.
- Multiple industrial communication protocols: Ethernet Modbus‑TCP and CANbus support SCADA / plant‑system integration.
- PC‑based commissioning: easYgen‑Tool software for offline configuration, firmware upgrade, fault‑log export and diagnostics.
Application Fields
‑ Cogeneration / CHP plants: Combined‑heat‑power generator‑set control ‑ Industrial power‑house: Multi‑generator‑set paralleling & load‑management ‑ Stand‑by power‑plants: Critical‑facility backup‑power automatic mains‑failure operation ‑ Oil‑gas & petrochemical: On‑site captive power‑generator‑control ‑ Hospital & data‑center: High‑reliability standby‑power‑management systems ‑ Retrofit‑maintenance projects: Spare‑part replacement for existing easYgen‑3500XT‑P2 installations
Product Advantages & Value
