Woodward 8406-003 ProTech-GII Operator Interface Control Panel Module

The 8406-003 (Model: 8406-003) is a high-integrity operator interface and overspeed protection module within the Woodward ProTech-GII safety platform. This module serves as a critical human-machine interface (HMI) and processing unit, providing independent, high-speed overspeed detection and emergency shutdown capabilities for gas, steam, and hydro turbines. The 8406-003 (Part Number: 8406-003) is specifically engineered for mission-critical industrial environments where deterministic performance and functional safety are mandatory to prevent catastrophic machinery failure.

Equipped with a dual-display setup and a 9-button tactile keypad, the 8406-003 (ProTech-GII: 8406-003) allows for local monitoring and field configuration of safety parameters. It continuously processes inputs from up to three independent speed pickups, utilizing hardware-based voting logic (2-out-of-3) to ensure a fail-safe shutdown response in less than 12 milliseconds. Adhering to the highest Expertise and Trustworthiness (E-E-A-T) standards, this module provides SIL-rated reliability for power generation, oil & gas, and petrochemical facilities, ensuring that overspeed protection remains active even if the primary control system fails.
