Applications & Industry Context
The TRICONEX 3501TN2 is widely deployed in industries where safety and reliability are critical, including oil & gas, petrochemical, chemical processing, power generation, and refining. Its primary purpose is to execute safety-critical logic and maintain high-integrity control in TMR safety systems.
In oil refineries, the 3501TN2 monitors and controls emergency shutdowns, flare systems, and pressure relief devices. In chemical plants, it ensures safe operation of reactors, pipelines, and hazardous process equipment. Power plants utilize it to manage turbine control, generator protection, and reactor safety interlocks.
Thanks to its rugged design, the 3501TN2 operates reliably under vibration, extreme temperatures, and electromagnetic interference, providing uninterrupted control and protection in environments where downtime is unacceptable.
Product Role & System Fit
The TRICONEX 3501TN2 serves as a CPU module within a TMR safety system, executing high-speed, deterministic logic for safety-critical applications. It communicates with I/O modules, monitors system health, and ensures continuous operation even in the event of hardware failures.
It integrates seamlessly into Triconex TMR platforms, forming the central processing unit of a triple redundant safety system. Its role is vital: by maintaining real-time control over safety interlocks and emergency shutdown systems, the 3501TN2 protects personnel, equipment, and the environment from hazardous conditions.
The module is suitable for both new installations and retrofits, providing scalability and redundancy for large industrial operations.
Technical Features & Benefits
The TRICONEX 3501TN2 offers several key advantages:
- High-Speed Processing: Executes safety logic deterministically and in real-time.
- Triple Modular Redundancy (TMR): Ensures continuous operation even if one or two modules fail.
- System Compatibility: Works with Triconex TMR safety platforms and I/O modules.
- Rugged Design: Resistant to temperature extremes, vibration, and electrical interference.
- Hot-Swappable: Can be replaced without interrupting system operation.
- Diagnostics & Monitoring: Built-in fault detection and system health monitoring for proactive maintenance.
These features make the 3501TN2 ideal for high-integrity industrial operations, where precise, reliable safety logic is essential to prevent accidents and production downtime.
