TRICONEX TRIPLE MODULAR REDUNDANCY

Tricon operation is based on the principle of safety and high plant availability, which identifies and

compensates for failed control system elements and allows on line replacement while continuing

its assigned task without interrupting the controlled process. Fault Tolerance is achieved through TMR technology.

TMR employs three isolated, parallel control systems and extensive diagnostics integrated into one

system. The Tricon system uses two-out-of-three (2oo3) voting to provide high integrity, error-free,

uninterrupted process operation with no single point of failure. Setting up applications is simplified

with the Tricon, because the TMR system operates as a single control system from the user’s point of

view. The extensive diagnostics are inherent and transparent to the programmer.

Use of the Tricon continues to expand into new industries and applications as customers require

increased system safety and/or high availability. Today, Invensys has delivered and installed Triconex

safety system solutions in over 70 countries, providing increased safety and high process uptime.

Managing operational risks with confidence

The Tricon fail-safe and fault-tolerant controller is used extensively in high-hazard industries 

where safe operations are critical and reliable operation is paramount. 

In particular, the Tricon system is the only commercial off-the-shelf controller approved by 

the Nuclear Regulatory Commission for Nuclear 1E applications.

Our safety and critical control solutions are supported by a dedicated team of TÜV-certified FunctionalSafety Experts and Engineers, 

deplo yed globally, ensuring that expertise is always available where and when required.

A powerful, scalable design with assurance of continuous operation,

the Tricon system complies with international standards such as IEC61508 and fulfills 

the requirements for applications such as Emergency Shutdown (ESD), Fire and Gas Protection (F&G), 

Burner Management (BMS),High Integrity Pressure Protection (HIPPS), and Turbo Machinery Control (TMC). 

The redundant high-availability architecture provides a flexible,robust, reliable, 

and powerful solution that is ideal for clients looking to achieve environmental and safety excellence.

ENSURING OPERATIONAL CONTINUITY AND MANAGING OPERATIONAL RISKS
