Description
WOODWARD 8440-2028 Digital I/O Expansion Module
The
WOODWARD 8440-2028 is a high-performance digital input/output (I/O) expansion module designed for industrial control systems, particularly in power generation, oil & gas, and automation applications. As part of Woodward’s IKD1 series, it extends the digital I/O capabilities of EASYGEN-3000 genset controllers or GCP-31/32 control packages, enabling seamless integration with generators, engines, and auxiliary equipment. The module supports CAN bus communication, offering flexible configuration and reliable operation in harsh environments. Key features include 8 configurable discrete inputs, 8 Form C relay outputs, and remote diagnostics for efficient system management.

- Flexible Expansion: Cascades up to 32 modules via CAN bus for scalable I/O capacity.
- Configurable Logic: Each input supports independent delay settings (0–60 seconds) and debounce filtering.
- Reliable Operation: Built-in transient protection and reverse polarity safeguards.
- Remote Monitoring: Real-time status updates and fault alerts via EASYGEN-3000 controllers.
- Space-Saving Design: Compact size (512 × 325 × 129 mm) for easy integration into control panels.
- Power Generation: Expands 报警输入 and relay outputs for generator set monitoring.
- Oil & Gas: Controls pumps and compressors in offshore platforms.
- Industrial Automation: Manages discrete signals in manufacturing lines.
Case Study:
A U.S. power plant improved generator efficiency by 12% using the 8440-2028 to add 24 new digital inputs for real-time equipment health monitoring.
Compared to standard I/O modules:
- Higher Scalability: Supports more cascaded modules than most mid-range solutions.
- Wide Voltage Range: Operates reliably across 10–30 VDC, reducing dependency on precise power supplies.
- Cost-Effective: Lower installation costs due to plug-and-play CAN bus integration.
- Controller Compatibility: Ensure compatibility with EASYGEN-3000 or GCP-31/32 systems.
- I/O Requirements: Calculate the number of inputs/outputs needed (each module adds 8/8).
- Environment: Opt for the IP54 protective cover for dusty or wet environments.
- CAN Bus Addressing: Assign unique addresses to avoid conflicts (0–31 range).
- Power Stability: Use a filtered power supply to prevent voltage spikes.
- Module Cooling: Install in well-ventilated enclosures to maintain temperature limits.
- Firmware Updates: Regularly update via Woodward’s LeoPC software for bug fixes.
