WOODWARD 5501-470 MicroNet Plus

The WOODWARD 5501-470 is a high-performance 32-bit CPU module for the MicroNet™ Plus / Simplex and NetCon™ control platforms, 

designed and manufactured by Woodward. It serves as the central processing unit for gas/steam turbines, reciprocating engines, and generator control systems, 

executing complex speed/load control algorithms, sequence logic, and network communication. Built for deterministic real-time performance 

and high reliability in harsh industrial environments (power generation, oil & gas, marine), it ensures stable, precise control of critical rotating equipment.
