Product Description
Woodward 5466-419 Rev B MicroNet TMR CPU Module
Product Overview
- The Woodward 5466-419 Rev B is a MicroNet Triple Modular Redundant (TMR) CPU Module designed for high-reliability control of industrial gas turbines, steam turbines, and compressors in critical applications, such as power generation, oil and gas, and marine systems. Part of Woodward’s MicroNet TMR control system, this microprocessor-based module serves as the central processing unit, executing complex control logic, managing I/O, and ensuring fault-tolerant operation through a triple-redundant architecture. The “Rev B” indicates a specific hardware or firmware revision, offering improved performance or features over earlier revisions. The 5466-419 provides real-time control, extensive diagnostics, and robust communication for integration into distributed control systems (DCS). Compared to the MicroNet Simplex CPU (e.g., 5501-381) or genset controllers (e.g., EasyGen-3200-5, 8440-2050E), the 5466-419 is optimized for safety-critical, high-availability turbine applications. It is distinct from Woodward’s protection relays (e.g., XD1G11), servo position controllers (e.g., 8200-226), communication modules (e.g., SST-ESR2-CLX-RLL), excitation systems (e.g., DECS-100-B15), electronic governors (e.g., DYN1-10784-003-0-12), and actuators (e.g., 8408-921).
