PRODUCT INFORMATION
Product Overview
The Woodward easYgen-3200-5 8440-1831 easYgen Controller is a dedicated generator set management device. It belongs to the Package P1 hardware release featuring a grayscale display. This unit provides comprehensive control, monitoring, and protection functions for generator sets. It coordinates engine governing and generator electrical operations through integrated communications. The controller supports standard industrial protocols across dedicated serial and CAN communication networks.
The 8440-1831 model incorporates two CAN interfaces and two distinct serial ports. It does not include an onboard Ethernet port in this Package P1 configuration. The primary CAN bus supports CANopen protocol with configurable baud rates up to 1000 kbaud. The secondary CAN channel concurrently executes CANopen and J1939 communication lines. Serial connectivity is handled via one RS-232 port and one RS-485 port.
