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.

Summary of Tricon

Components

Chassis

• Main Chassis—houses Main Processors, memory back-up batteries, communication modules and I/O modules.

• Expansion Chassis—for additional I/O modules up to 100 feet (30meters) away from the Main Chassis. In restricted applications,

operation up to 1,000 feet (300 meters) is supported.

• RXM Chassis—for I/O modules up to 7.5 miles (12 kilometers) away from the Main Chassis.

• Mechanical Keying—Each slot in the Tricon is mechanically keyed to correspond with a specific type of module. 

This prevents the installation of modules into improper slots.

Power Supply Modules

• Provide logic power to modules in the Main, Expansion or RXM

Chassis. Available in 24 VDC, 115 VAC and 230 VAC versions. The

power rating of each power supply is 175 watts at 140 ° F (60° C).

Main Processors

The Main Processors execute the system diagnostics and the user-written control program.
