Product Description
The 5466-1045 MicroNet Plus CPU5200 is a panel-mounted digital control processor engineered by Woodward for secure turbine and engine control systems. This controller belongs to the MicroNet Digital Control platform and is intended for GAP-based applications where deterministic control, compact architecture, and certified hazardous-area operation are required.
Unlike RTN-enabled MicroNet CPUs, this model operates as a standalone controller and is not designed for expansion chassis or real-time network backplanes. It is commonly deployed as a cyber-secure upgrade replacement for legacy CPU5200 hardware in existing installations.
Key System Architecture
The 5466-1045 CPU5200 integrates processing, memory, and field communication in a single controller module. It does not provide RTN ports and therefore functions without remote expansion racks. Control logic is executed using GAP application programming, supported by CPU_ML5200 diagnostics.
This model is identified by Woodward as an approved replacement for earlier CPU5200 variants, including 5466-1036/6, when migrating systems to cyber-secure operating environments. For extended performance and memory capacity, Woodward recommends 5466-1510 as the long-term successor.
Memory and Processing Resources
The controller is built on a legacy CPU5200 hardware platform optimized for deterministic control rather than high-capacity computation.
- Flash Memory: 64 MB
- DDR RAM: 128 MB
- Architecture Note: Provides approximately one-eighth the RAM and one-sixth the flash capacity of later P1020-based MicroNet CPUs
These resources are suitable for traditional GAP control strategies commonly used in gas turbine and engine control systems.
Communication Interfaces
The 5466-1045 includes essential onboard interfaces for system integration, configuration, and diagnostics.
- Ethernet Port: 1 general-purpose Ethernet interface
- CAN Ports: Dual CAN channels for field device communication
- Serial Interface: 9-pin COM port
- Service Port: Dedicated maintenance and commissioning access
- Remote Reset Input: +24 V DC nominal response
RTN networking and expansion chassis communication are not supported.
Environmental and Regulatory Ratings
- Operating Temperature Range: –40 °C to +85 °C
- Shock Resistance: MIL-STD-810C
- Regulatory Approval: North American CSA Class 1 Division 2
- Weight: 2.00 lbs
Typical Applications
The 5466-1045 is commonly used in:
- Gas turbine control systems
- Reciprocating engine management
- Mechanical drive control packages
- Legacy MicroNet Plus installations requiring cyber-secure OS upgrades
FAQ
Is this controller compatible with RTN expansion racks?
No. The 5466-1045 does not include RTN ports and cannot operate with expansion chassis or remote I/O racks.
Can this module replace older CPU5200 controllers?
Yes. It is widely used as a direct replacement for 5466-1036/6 during field upgrades, particularly when cyber-secure firmware is required.
What is the recommended newer alternative?
Woodward identifies 5466-1510 as the preferred replacement when higher memory capacity or newer CPU architecture is needed.
