Description

The MicroNet TMR® control platform features a ruggedized rackmount chassis with in-line replaceable I/O modules and triple modular architecture for 99.999% availability.

This triple modular redundancy-based system consists of three independent cores (A, B, and C) housed in the platform’s compact chassis.

Each core section includes its own CPU, CPU power supply, and up to four I/O modules, which can be used for simplex I/O, redundant I/O, triple redundant I/O, or any combination of redundancy.

I/O can be expanded via a system expansion chassis or the ruggedized LinkNet HT Distributed I/O.

The platform’s high-density modules and integrated application software reduce troubleshooting time by providing first-out indication of monitored system events.

These specialized modules can time stamp discrete events in 1 millisecond and analog events in 5 milliseconds.

The MicroNet TMR® utilizes two power supplies, each supplying power to the controller from a separate power source. Within each power supply are three independent power converters, one each for the CPU and I/O sections.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.
