Product Description

The Woodward 5501-470 is a high-performance central processing unit (CPU) module designed for MicroNet Plus and MicroNet Simplex control platforms. Built on the robust Motorola MPC5200 architecture, this module is the primary intelligence for large-scale turbine and engine management systems. It handles complex, high-speed control algorithms and sequence logic with deterministic execution, ensuring critical industrial processes remain stable and responsive.

The 5501-470 features an integrated Real-Time Operating System (RTOS), facilitating high-speed data exchange across the MicroNet backplane. With dual Ethernet ports for redundant networking and serial ports for diagnostics or Modbus integration, this module is built for reliability in high-vibration and thermally volatile environments typical of power generation and mechanical drive facilities.

Industrial Application Scenarios

The 5501-470 is commonly used in MicroNet Plus systems controlling multi-spool gas turbines, large steam turbines, and compressor sets. It is also frequently deployed in "Hot-Replacement" redundant configurations, where a secondary CPU automatically takes over control within milliseconds if the primary unit fails.

Engineering FAQ

Does the 5501-470 require an external power supply?

No, the 5501-470 draws its operating power directly from the MicroNet Plus chassis backplane, which is powered by the system's redundant power supply modules.

Can I upgrade an older 586-based CPU with this module?

Upgrading from an older 586-based CPU may require migration of the GAP® (Graphical Application Programmer) software and potentially a revision of the backplane, as the 5501-470 offers superior processing power.

How is the firmware updated on this unit?

Firmware and application code are typically loaded through the primary Ethernet port using Woodward's proprietary AppManager software tools.
