Triconex 8312 Output module

Triconex Critical Modules Overview

Triconex (now a brand of Schneider Electric) is renowned for its high-integrity, fault-tolerant safety systems widely used in oil and gas, chemical, power generation, and other high-hazard industries. Triconex critical modules are the core components of these safety systems, designed to provide the highest levels of safety and availability.

Product Detailed Description

Triconex critical modules cover various aspects of the safety system, including:

• Main Processor Modules: Execute safety logic and manage the overall operation of the system. Typically employ a Triple Modular Redundant (TMR) architecture to eliminate single points of failure.

• Input/Output (I/O) Modules: Interface with field sensors and actuators, receiving process data and sending control signals. Available in various types, including analog input, analog output, digital input, and digital output, often supporting redundant configurations.

• Communication Modules: Enable communication between the Triconex system and other control systems, monitoring systems, or plant networks, supporting various industrial protocols.

• Power Supply Modules: Provide redundant power to the Triconex system, ensuring continuous operation even in the event of a power failure.

• Network Modules: Used to build redundant Triconex safety networks, connecting multiple Triconex chassis or systems.
