The Woodward MicroNet TMR is a triple modular redundant digital control platform engineered for the most safety-critical and economically critical turbine and compressor applications. Its 2-out-of-3 voting architecture delivers 99.999% availability, with online module replacement and IEC 61508 SIL-3 compliance when paired with the MicroNet Safety Module. The MicroNet TMR is the hardware foundation for the 5009FT steam turbine control.
