Product Model: TRICONEX 3401
Product Brand: TRICONEX
Product Series: Tricon / Safety System CPU Modules
Product Features:
- High-speed CPU designed for triple modular redundant (TMR) safety systems
- Executes deterministic safety-critical logic for industrial processes
- Compatible with Triconex TMR safety platforms
- Rugged and reliable for harsh industrial environments
Applications & Industry Context
The TRICONEX 3401 is widely used in industries where safety and reliability are non-negotiable, including oil & gas, chemical processing, petrochemical, power generation, and refining. It forms the central processing unit (CPU) of a Triconex TMR system, providing deterministic execution of safety-critical logic.
In oil refineries, the 3401 monitors emergency shutdown systems, flare stacks, and pressure relief devices. In chemical plants, it protects reactors, pipelines, and processing equipment by executing rapid safety interlocks. Power generation facilities use it to manage turbine and generator protection systems, ensuring safety and continuous operation.
The module’s rugged design ensures operation in high-temperature, high-vibration, and high-electrical-noise environments, making it a reliable choice for mission-critical safety applications.
Product Role & System Fit
The TRICONEX 3401 serves as a CPU module within a triple modular redundant safety system, executing high-speed logic for safety-critical processes. It communicates with input/output modules, monitors system health, and ensures continuous operation even if one or more modules fail.
Its primary role is to maintain safety integrity and deterministic control, ensuring that emergency shutdowns, alarms, and interlocks are executed accurately and promptly. Compatible with Triconex TMR platforms, it is suitable for both new installations and system upgrades, offering seamless integration with existing safety architectures.
By maintaining consistent and reliable control, the 3401 module protects personnel, equipment, and the environment, reducing the risk of accidents and unplanned downtime.
