The Tricon is a state-of -the-art fault tolerant controller based on a Triple-Modular Redundant (TMR) architecture. It was the first completely triple-redundant, industrially ruggedized and cost-effective safety instrumented system in the industry and our most trusted safety controller.
TMR employs three isolated, parallel control systems and extensive diagnostics integrated into one system. The system uses two-out-of-three 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 Triplicated 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. All diagnostic information is stored in system variables and available to the user.
Use of the Tricon continues to expand into new industries and applications as customers require increased system safety and/or high availability. Today, Triconex has installed Tricon safety systems in over 50 countries, providing increased safety, reliability and availability to a worldwide installed base. The following are a few typical applications:
