Triconex Model 3481 Analog Output Module

Tricon and Tricon CX  High-integrity +  high-availability system

The TriconTM high-integrity/high-availability system meets the needs of safety and critical

control applications in oil and gas, power, refining, chemicals, pharmaceutical, and biotech  industries.

It is based on industry-leading TMR technology, is easy to operate and maintain,  and provides a higher value of ownership.

SAFE • AVAILABLE • SECURE

Schneider ElectricTM is the only automation

company with the experience and track

record in safety and critical control with

more than 30 years of safety system

experience. It is also the only automation

company with more than 13.000 safety

systems installed in more than 80 countries

and operating for more than 1 billion hours.

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.
