Woodward MicroNet TMR Triple Modular Redundant Controller Control System

Applications

MicroNet TMR® (Triple Modular Redundancy) controllers are state-of-the-art digital control

platforms designed to reliably control and protect steam turbines, gas turbines and compressor packages.

These units are used in critical system applications where there is a risk of safety issues or significant economic loss.

The MicroNet TMR®'s "2-out-of-3" voting structure ensures that problems are responded to correctly

and that prime movers continue to operate safely with or without any single point of failure.

The controller's robustness, fault tolerance, accuracy and availability make it the first choice

for turbine and compressor OEMs and operators worldwide.

The superior architecture and diagnostic coverage of the MicroNet TMR® results in 99.999%

system availability and reliability.

The MicroNet TMR® can be

MicroNet TMR® can be used as a component of a protection and safety system,

making the entire system compliant with IEC61508 SIL-3.

IEC61508 calculation and application assistance.

 Typical MicroNet TMR® application experience and use:

 Refrigeration compressors (ethylene, propylene)

 Methane and Syngas Compressors

 Gas Cracking Compressors

 Gas charging compressors

 Hydrogen Recovery Compressors

 Critical turbine generator sets

 Turbine Safety Systems

For IEC61508 SIL-3 based applications, MicroNet systems require a MicroNet Safety Module (MSM).

The MSM serves as the system's SIL-3 logic solver, and its fast (12 ms) response time and integrated

overspeed and acceleration detection/protection make it ideal for critical high-speed rotating motor, compressor, turbine or engine applications.
