8440-1257B

Woodward 8440‑1257B is the easYgen‑2200‑5, a compact, cost‑effective digital genset controller in the easYgen‑2000 series. It provides single‑set monitoring, protection, automatic start/stop, voltage regulation, basic synchronization and island‑mode parallel capability for diesel/gas generator sets. Widely used in industrial backup power, commercial standby power, marine auxiliary power and oil‑gas small‑scale power systems.

Description

Core Functions

  1. Automatic start‑stop, fault detection, shutdown protection and alarm functions.

  2. Built‑in voltage regulation, frequency monitoring and overspeed protection.

  3. Basic single‑unit synchronization and simple parallel operation for small‑scale gensets.

  4. Comprehensive engine protection: low oil pressure, high coolant temperature, over‑crank, over‑voltage, under‑voltage, overload, reverse power.

  5. Communication: Modbus‑RTU, J1939 CAN bus for engine data monitoring; configurable via easYgen configuration software.

  6. Panel‑mount with integrated LCD display and push‑buttons for local operation.
