Product Overview
The Woodward 8440-2056 is a genset control unit from the easYgen-3000 series, specifically the 3100 version. Designed for cabinet back mounting, this 8440-2056 module does not include a built-in HMI; instead, programming, monitoring, and control are performed via PC using the ToolKit software. It features 5A CT inputs and three freely configurable PID controllers, all housed in a robust metal enclosure. Part 8440-2056 supports both single and multi-unit generator operations, with automatic sequencing for up to 32 gensets.

Industry Applications
The Woodward 8440-2056 excels in demanding power generation environments. Typical applications include:
-
Prime Power Gensets: Reliable control for continuous or standby generator sets in hospitals, data centers, or industrial facilities. The wide voltage and current setting ranges allow adaptation to various generator ratings.
-
Multi-Unit Paralleling: With peer-to-peer paralleling functionality and automatic sequencing of up to 32 generators, the 8440-2056 reduces system complexity while providing load-dependent start/stop and mains parallel operation.
-
Cogeneration and Peak Shaving: The unit's three PID controllers enable precise fuel and air-ratio control for gas engines, optimizing efficiency and lowering emissions over time.
These capabilities directly contribute to lower total cost of ownership by minimizing downtime and simplifying maintenance.
Installation & Setup Guidance
Mount the Woodward 8440-2056 securely inside a metal control cabinet using the provided back-panel slots. Ensure adequate airflow around the module to prevent overheating. Connect the DC power supply within the 8–40 Vdc range, verifying polarity and using appropriate fusing. For CT inputs, use 5 A secondary current transformers and observe correct phasing. Programming is performed via a PC running Woodward's ToolKit software; connect using a USB or serial interface as described in manual 37258P. After configuration, test each operating mode (Automatic, Manual, Stop, Test) to confirm proper breaker control and frequency/voltage setpoints.
Maintenance & Reliability
The 8440-2056 is built with robust components in a metal housing, ensuring long service life even in harsh industrial environments. To maximize ROI, follow a routine maintenance schedule:
- Inspect and clean the unit every 6–12 months, especially in dusty or humid conditions.
- Verify that all wiring terminals remain tight and free of corrosion.
- Test the real-time clock event recorder and counters monthly to ensure accurate logging of operating hours and maintenance triggers.
- Regularly update the firmware via ToolKit to benefit from performance improvements and bug fixes.
Proactive maintenance reduces unexpected failures and extends the intervals between major overhauls.
Buying Guide & Selection Advice
Before purchasing the Woodward 8440-2056, confirm that your generator system requires a 5A CT input and that the DC supply range (8–40 Vdc) is available. This module does not include a local HMI, so ensure you have a PC with Woodward ToolKit software for commissioning and monitoring. For multi-unit setups, verify that all units will be from the easYgen-3000 series to enable peer-to-peer communication. When ordering from PLC Source PRO (formerly ubest101), specify the exact part number 8440-2056 and quantity needed. Our inventory includes genuine Woodward products with fast shipping worldwide.
