8406-003 Woodward Overspeed Protection Display Module

8406-003 Woodward Overspeed Protection Display ModuleProduct Overview The Woodward 8406 003 serves as the high integrity processing module and operator interface for the ProTech GII safety platform. This unit provides the essential Human Machine Interface (HMI) for turbine overspeed detection, allowing operators to monitor real time speed data and configure critical safety parameters locally. Designed for steam, gas, and hydro turbines, the 8406 003 maintains autonomous protection, ensuring an emergency

keeping the field outputs steady

The 9905-976 (Model: 9905-976) is a high-integrity digital overspeed protection system designed for the most critical turbine safety applications

operates as a dedicated hardware component for mechanical support and electrical communication backbone within MicroNet Plus platform networks

Does the 8200-1302 support remote I/O expansion

Tighten the rear mechanical retention clamps evenly to compress the perimeter gasket without distorting the front bezel

Triple Modular Redundancy for Critical Safety Logic

Flexible Signal Configuration: The module accommodates both voltage and current output requirements

The Fault Tolerant Ethernet driver assigns a single

This provides reliable execution of binary blocks during firmware upgrades through Woodward ServiceTool or Toolkit software suites

The protection panel is built on a Triple Modular Redundant (TMR) 2oo3 architecture that uses three separate internal microprocessors to monitor three independent speed sensing pickups

The Allen-Bradley 1769-IF4XOF2 serves as a high-efficiency interface for the CompactLogix and MicroLogix 1500 PLC platforms
