Woodward 9563-810 PLC Module | Industrial Leakage and Fault Protection

Product Description

The Woodward 9563‑810 Leakage Monitoring Module is a high-performance protection device designed for medium- and high-voltage electrical distribution systems, typically rated at 660 V and 1140 V. It continuously monitors leakage currents and system parameters, automatically triggering protective actions when abnormal conditions are detected.

This module integrates leakage detection, short-circuit protection, over/under-voltage monitoring, and over-temperature safeguards into one compact unit, ensuring maximum reliability and safety in industrial environments. Moreover, built-in test buttons allow operators to verify feeder protection at any time, simplifying maintenance and commissioning.

The 9563‑810 is widely used in industrial switchgear, mining power systems, and heavy electrical distribution networks, where personnel safety and equipment reliability are critical. Its robust design makes it suitable for demanding high-voltage environments and continuous industrial operation.
