Product Overview

The Woodward 8406-120 is a key component of the GCP-31 (Generator Control Package) series. It manages the synchronization, load sharing, and protection of single or multiple generator sets, ensuring stable power grid interaction and emergency standby operations. The module provides automated control logic and integrates multiple inputs to monitor critical system parameters.

Technical Specifications

Engineering Advantages

• Automated Synchronization Logic: The 8406-120 calculates the phase angle, frequency, and voltage differences between the generator and the busbar. It automatically adjusts engine speed and excitation for seamless grid synchronization, ensuring a bumpless connection.

• Comprehensive Engine-Generator Protection: By integrating multiple protection functions (overcurrent, reverse power, and frequency protection) into a single module, the 8406-120 reduces wiring complexity and failure points within the control cabinet.

• Flexible 4-Input Monitoring: The module allows for monitoring 4 critical parameters (e.g., oil pressure, coolant temperature, fuel levels). It can trigger alarms or shutdowns based on these real-time values, providing essential protection for the engine.

• Deterministic Load Sharing: In multi-engine setups, the GCP-31 logic ensures proportional load sharing across generators, preventing smaller units from being overloaded and optimizing fuel efficiency.

• Industrial-Grade Housing: The ruggedized chassis is designed to withstand electromagnetic interference (EMI) and mechanical vibrations typical in industrial environments, ensuring stable operation in diesel and gas engine skids.

FAQs

Is this Woodward 8406-120 module a brand new unit?

Yes, we supply only 100% brand new and original Woodward 8406-120 modules, ensuring full compliance with manufacturer standards and operational integrity.

Does the 8406-120 support remote monitoring?

Yes, the module includes communication ports for integration with PC-based service tools or SCADA systems. This allows operators to remotely monitor generator performance and adjust settings without accessing the high-voltage switchgear.

Can this module replace older GCP-20 series controllers?

The 8406-120 is a more advanced model in the GCP-31 family, offering enhanced features. However, be sure to verify terminal pinouts and mounting dimensions as they may differ from older GCP-20 controllers.

What happens if the 24 VDC power supply fluctuates?

The module features an internal voltage regulator that can handle typical fluctuations of ±15%. For optimal performance, a stable, filtered power source is recommended to ensure precise operation.
