The Tricon™ platform is the gold standard in safety instrumented systems.
Overview
Based on industry-leading Triconex™ triple modular redundant (TMR) technology, Tricon has logged more than one billion hours with no failure on demand. The Tricon system is certified by TÜV Rheinland for use in safety applications up to Safety Integrity Level 3 (SIL 3). It is also marine-certified and nuclear 1E-certified.

Full set of software tools for every stage of the safety life cycle (TriStation™ suite)
What is the Tricon?
The Tricon is a state-of-the art controller that provides fault tolerance by means of Triple-Modular Redundant (TMR) architecture. TMR integrates three isolated, parallel control systems and extensive diagnostics in one control system. The system uses two-out-ofthree voting to provide high-integrity, error-free, uninterrupted process operation with no single point of failure.
A Tricon system is composed of a main chassis and up to 14 expansion or remote expansion (RXM) chassis. The maximum system size is 15 chassis supporting a total of 118 I/O modules and communication modules that interface with OPC clients, Modbus devices, other Tricons, and external host applications on Ethernet (802.3) networks, as well as Foxboro and Honeywell distributed control systems (DCS).
