Industry Applications
The Woodward 8440-1956 excels in engine generator control for easYgen-3000 systems. It handles generator voltage monitoring in delta or wye configurations, making it suitable for isolated or compensation networks. The wide setting range from 0.5 to 99,999.9 kW/kvar allows precise power measurement across diverse generator sizes. Multiple alarm classes (A through F) enable customized protection schemes.
Installation & Setup
When installing the Woodward 8440-1956, inspect the metal frame for any damage before mounting. Ensure proper voltage monitoring configuration: for isolated or compensation networks, set voltage monitoring to wye (phase-neutral) to prevent earth faults and unintended tripping. The module's 1 A CT input simplifies integration with existing current transformers.
Maintenance & Reliability
The Woodward 8440-1956 operates reliably in high humidity environments up to 95% non-condensing. The AgCdO contact material ensures durable switching performance. With accuracy class 0.5, this module minimizes measurement errors, reducing downtime and maintenance costs. Its robust design supports long-term operation in demanding industrial settings.
Selection Guide
When selecting the Woodward 8440-1956, verify that your application requires the P1 form factor (smaller size, fewer I/O) rather than the P2 variant. The module is available from PLC Source PRO (formerly ubest101) – a trusted supplier of industrial automation spares. Confirm compatibility with your generator control system before ordering.
