Triconex Tricon Fault-Tolerant Controller

upset conditions, safety

interlock for normal startup and shutdown, and flame-safety applications are

combined by one integrated Tricon system. In traditional applications, these

functions had to be provided by separate, non integrated components.

But with the fault-tolerant, fail-safe Tricon controller, the boiler operations staff

can use a critical resource more productively while maintaining safety at or

above the level of electromechanical protection systems.

Turbine Control Systems

The control and protection of gas or steam turbines requires high integrity

as well as safety. The continuous operation of the fault-tolerant Tricon

controller provides the turbine operator with maximum availability while main

taining equivalent levels of safety.

Speed control as well as start-up and shutdown sequencing are implemented

in a single integrated system. Unscheduled outages are avoided by using hot

spares for the I/O modules. If a faultoccurs in a module, a replacement

module is automatically activated without operator intervention.

Offshore Fire and Gas Protection

The protection of offshore platforms from fire and gas threats requires

continuous availability as well as reliability. The Tricon provides this avail

ability through online replacement of faulty modules. Faults in individual

modules, field wiring and sensors are managed automatically by built-in

diagnostics. Analog fire and gas detectors are connected directly to the

Tricon, eliminating the need for tripamps. An operator interface monitors

fire and gas systems as well as diagnostics for the Tricon controller and its

attached sensors. Traditional fire and gas panels can be replaced with a single

integrated system, saving costly floor space while maintaining high levels of

safety and availability.
