Woodward 5466-1510 MicroNet P1020 / TMR CPU5200 CPU Module

Product Overview

5466-1510 is a high-performance control processor module manufactured by Woodward for use in MicroNet and MicroNet TMR control platforms. Depending on the system configuration, this module operates either as a MicroNet P1020 CPU or as the enhanced CPU5200 processor within a Triple Modular Redundant (TMR) architecture.

The module functions as the computational core of the control system, executing deterministic real-time algorithms, coordinating system communications, and maintaining operational integrity in high-availability turbine and compressor control environments.

Functional Characteristics

The processor is built on a PowerPC P1020 dual-core architecture, delivering stable real-time performance for continuous industrial operation. It supports simplex, redundant, and TMR system designs, enabling fault tolerance, online maintenance, and long-term system scalability.

Primary responsibilities include real-time logic execution, system timing management, redundancy synchronization, and high-speed data exchange with I/O and communication modules.

Clarification on Market Descriptions

Some third-party listings describe 5466-1510 (P/N 5466-1510) as a “Remote I/O Interface Module.” This classification is not part of the official Woodward product definition. The module is a central processing unit and interfaces with I/O through dedicated MicroNet communication and I/O modules rather than acting as an independent remote I/O controller.

Typical Applications

• Gas turbine control systems
• Steam turbine and combined-cycle power plants
• Industrial compressor control and anti-surge systems
• Oil, gas, and energy infrastructure with rotating equipment
• Safety-critical control systems requiring TMR architecture

Frequently Asked Questions

Q: Does the 5466-1510 support online replacement? A: In MicroNet P1020 configurations, live insertion and removal are supported, subject to system architecture and redundancy design.

Q: Can this module be used as a standalone I/O controller? A: No. This unit operates as a system CPU and requires MicroNet I/O and communication modules for field signal handling.

Q: Is the module suitable for safety-critical applications? A: Yes. When deployed in a MicroNet TMR system, it serves as part of a triple-redundant control architecture designed for high availability and fault tolerance.
