Fault tolerance in the Tricon family produced by Triconex is achieved through a 'triple modular redundant' (TMR) architecture. The Tricon provides error-free, uninterrupted control in the presence of either hard failure of components, or transient faults from internal or external sources. They are designed with a fully triplicated architecture throughout, from the input modules, through the main processors, to the output modules; every I/O module contains the circuitry for three independent legs. Each leg on the input modules reads the process data and passes the information to its respective main processor. The three processors communicate with each other over the chassis backplane using a proprietary high-speed bus system called the Tribus.

A field termination panel, and associated wiring, passes input signals from the field to an input module, or passes signals generated by an output module directly to the field wiring, thereby permitting insertion, removal or replacement of the I/O modules without disturbing the field wiring.

Triconex has provided hundreds of turnkey safety systems for a large number of applications in the oil and gas, refining, chemical, electric utilities and food processing industries. Triconex also works with a worldwide network of systems integration partners to implement virtually any application.

Since its founding in 1983, Triconex has become a world leader in the supply of products, systems and services for safety, critical control and turbo machinery applications. (The company is represented throughout southern Africa by AFH Devers.)

In 1994, Triconex was acquired by Siebe, one of Britain's largest diversified engineering groups, and a leader in global engineering and process control solutions. More recently, Siebe merged with BTR to create a leading electronics and engineering group, called Invensys.

Triconex operates in the area of risk analysis, safety assessment and risk reduction, which allows the client to attain more cost effective solutions by establishing safety and performance goals early in the design process. The group can deliver reliable turnkey safety/emergency shutdown, critical control, burner management, turbo machinery and fire and gas solutions, claiming over 60% of the world market share.
