TMR Processor

Introduction

The Trusted

TM

Processor forms the main processing element in a Trusted

TM

system, providing overall

system control and monitoring facilities.

A powerful, user-configurable module, the Trusted

TM

TMR Processor processes input and output data

through a variety of analogue and digital I/O modules via a Trusted

TM

TMR Communications bus.

The range of applications for the Trusted

TM

TMR Processor vary in integrity level and include fire and

gas control, emergency shutdown, monitoring and control, and turbine control.
