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.

This triple power supply structure provides maximum protection against single or multiple points of

hardware failure.

The controller’s dedicated TMR® Discrete I/O Module is designed for critical discrete circuits.
