The 8440-1831 (Model: 8440-1831) is a sophisticated genset management controller and operator interface within Woodward’s easYgen-3200 series. Designed as a comprehensive Human-Machine Interface (HMI), it provides localized control and monitoring for complex power generation systems, including single-unit and multiple-unit load sharing. The 8440-1831 (Part Number: 8440-1831) features a clear 4.5 x 3.5-inch screen that offers real-time visualization of engine parameters, electrical values, and system status.
Beyond a simple display, the 8440-1831 (Model: 8440-1831) incorporates FlexIn technology, allowing it to interface with various analog sensor types (0/4–20 mA, resistive, or VDO) without requiring external signal converters. It is specifically rated for 0.5A CT secondary and 100-400 VAC PT secondary inputs, making it ideal for standard industrial generator configurations. With integrated Modbus communication, the unit seamlessly bridges field-level generator data to higher-level SCADA or building management systems.
The 8440-1831 (Model: 8440-1831) is engineered for deterministic power management and precise electrical measurement.
