Product Description
Woodward 5458-051 MicroNet TMR Analog I/O Module
Product Overview
- The Woodward 5458-051 is an Analog Input/Output (I/O) Module designed for Woodward’s MicroNet Triple Modular Redundant (TMR) Control Systems. This module processes analog signals for both input and output, interfacing with sensors and actuators in critical industrial applications such as gas and steam turbines, compressors, and power generation systems. Its TMR architecture ensures fault-tolerant operation through triplicated signal processing with 2-out-of-3 voting, making it suitable for high-reliability environments. The 5458-051 is commonly used in industries like power generation, oil and gas, aerospace, and marine, known for its robust design and seamless integration with MicroNet TMR systems. It is similar to the Woodward 5458-050 but may feature specific configuration or firmware differences.
