WOODWARD 8440-2028 – Digital I/O Expansion Module | Easygen-3000 Series Platform
Engineering Background
WOODWARD is a globally recognized leader in energy control solutions, specializing in governor systems, generator management, and industrial automation hardware. The Easygen-3000 series represents WOODWARD’s flagship genset controller platform, widely deployed in power generation, marine propulsion, and critical infrastructure applications worldwide.
Product Positioning
The WOODWARD 8440-2028 is a dedicated Digital I/O Expansion Module engineered to extend the discrete signal capacity of Easygen-3000 series controllers. It is the preferred solution for system integrators and OEM panel builders who require additional digital inputs and outputs beyond the base controller’s native I/O count — without compromising system integrity or communication latency.

- Wide Temperature Range: Qualified for harsh ambient conditions from arctic to tropical deployments.
System Architecture & Signal Flow
The 8440-2028 connects directly to the Easygen-3000 controller via the internal expansion bus. Digital input signals (dry contact or voltage-level) are conditioned and mapped to the controller’s I/O address space. Digital output channels drive relay coils, solenoids, or indicator circuits under direct PLC ladder/function-block program control. The module is transparent to the Easygen-3000 configuration software — all I/O points appear natively within the controller’s tag database.

Technical FAQ
Q: Is the 8440-2028 compatible with Easygen-2000 series controllers?
A: No. The 8440-2028 is specifically designed for the Easygen-3000 platform. Easygen-2000 uses a different expansion bus architecture.
Q: How many 8440-2028 modules can be stacked on a single Easygen-3000 controller?
A: The maximum number of expansion modules is defined by the Easygen-3000 hardware configuration guide. Please consult WOODWARD manual 26175 or contact us for application-specific guidance.
Q: Can I configure the I/O points using Easygen-3000’s standard configuration tool?
A: Yes. All I/O points on the 8440-2028 are fully accessible and configurable within the Easygen-3000 configuration software without additional drivers.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 3–5 business days. For large quantities or special requirements, contact us for a dedicated lead time assessment.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, CoC and inspection reports are available upon request for verified surplus units.
