Description
The Woodward 8440-1887 is an advanced Automatic Transfer Switch (ATS) Interface designed to complement the easYgen-XT control series. This module serves as a bridge between the primary power management controller and the mechanical transfer switch gear. It ensures that data regarding the status of the power sources and the physical position of the switch is communicated accurately, facilitating safe, coordinated, and reliable power transitions during utility failures or scheduled maintenance.
Technical Specifications
- Series: easYgen / ATS Management
- Device Type: ATS Interface Module
- Application: Power Transfer Control and Monitoring
- Dimensions: 224 mm x 160 mm x 60 mm (approximate)
- Weight: 0.9 kg

Key Features
- 🔄 Synchronized Command Execution: Ensures that the mechanical transfer switch operates only when the controller has verified that the backup power source is stable and ready to accept load.
- 🛡️ Status Feedback Monitoring: Provides real-time, high-integrity feedback on the physical position of the switch (Utility, Neutral, or Generator position).
- ⚙️ Operational Reliability: Designed to operate in high-availability environments, ensuring that emergency power systems activate with minimal latency.
- 🔌 System Compatibility: Specifically engineered to integrate within the Woodward ecosystem, allowing for “plug-and-play” communication with easYgen-3200XT and 3500XT controllers.
Frequently Asked Questions
❓ Is the 8440-1887 a standalone controller?
No, it is primarily an interface/extension module. It is intended to work in conjunction with an easYgen controller, which handles the main decision-making logic for the generator and utility grid.
❓ What does “Interface” imply in this context?
It implies that the module handles the translation of high-voltage status signals from the switch gear into low-voltage digital inputs that the controller can safely process, while also relaying the controller’s switching commands back to the mechanical switch.
❓ Why is this interface necessary for ATS applications?
In large-scale power systems, it is vital to isolate the controller from the high-voltage environment of the switch gear. This interface provides the necessary electrical isolation and signal conditioning to protect the main control system from surges and electrical noise.
