TRICONEX 3101 Product Specification
Product Overview
The TRICONEX 3101 is a high-reliability Triple Modular Redundant (TMR) main processor module designed for safety-critical industrial automation systems. As a core component of TRICONEX’s Trident platform, it executes complex control logic, processes real-time data from field devices, and ensures seamless operation of safety instrumented systems (SIS) in environments where failures could lead to catastrophic consequences.
The TRICONEX 3101 features three independent processing channels that operate in parallel, continuously comparing outputs to detect and isolate faults. This architecture ensures fault tolerance and maintains system integrity even if one or two channels fail, making it ideal for applications like emergency shutdown systems (ESD) in oil refineries or burner management systems (BMS) in power plants. Certified to IEC 61508 SIL 3, the module meets the highest safety standards, minimizing the risk of dangerous failures and ensuring compliance with global industrial regulations.
Built to withstand extreme conditions, the TRICONEX 3101 operates reliably in temperatures ranging from -40°C to +70°C and handles humidity up to 95% (non-condensing). Its compact design (259 mm × 160 mm × 79 mm) and rugged construction enable easy installation in standard control cabinets across industries such as chemical processing, nuclear power, and water treatment.

Main Features and Advantages
Triple Modular Redundancy (TMR): The TRICONEX 3101 uses three identical processing channels to execute the same logic simultaneously. Outputs are continuously compared, and any deviating channel is isolated, ensuring fault tolerance. This design eliminates single points of failure, critical for applications like nuclear reactor control, where downtime is unacceptable.
SIL 3 Compliance: Certified to IEC 61508 SIL 3, the module is suitable for high-risk environments, such as offshore oil platforms, where safety is paramount. It reduces the probability of dangerous failures by 99.9%, ensuring emergency shutdowns or interlocks are executed correctly when needed.
High-Speed Processing: The Motorola MPC860 processor delivers real-time responsiveness, allowing the TRICONEX 3101 to detect anomalies (e.g., pressure spikes) and trigger protective actions within milliseconds. This is vital in fast-paced processes like chemical batch reactors.
Rugged Durability: The module operates reliably in extreme temperatures (-40°C to +70°C) and resists dust, vibration, and electromagnetic interference. Its IP66-rated casing makes it suitable for harsh outdoor environments, such as desert refineries or humid water treatment plants.
Hot-Swap Capability: The TRICONEX 3101 can be replaced while the system is running, minimizing downtime during maintenance. This feature is critical in 24/7 operations, such as petrochemical plants, where even brief outages can lead to production losses.

Installation and Maintenance
Pre-installation preparations: Before installing the TRICONEX 3101, power off the TMR rack and verify the input voltage matches the TRICONEX 3700A power supply (24 VDC). Clean the rack slot to remove debris and ensure proper alignment. Slide the module into the slot until it locks, then secure it with front panel screws to maintain a stable backplane connection.
Maintenance suggestions: Inspect the TRICONEX 3101 monthly for loose connections, discoloration (indicating overheating), or corrosion. Wipe dust from the module with a dry cloth. Quarterly, simulate a fault in one channel using system software to test redundancy, ensuring the remaining channels continue processing without errors. If the fault LED remains illuminated, replace the module immediately to uphold system safety.
Application Fields
Oil and Gas: The TRICONEX 3101 serves as the core of emergency shutdown systems (ESD) on offshore platforms. It processes data from pressure and flow sensors, triggering valve closures or pump shutdowns to prevent leaks during storms or equipment failures.
Chemical Processing: In batch reactors, the module monitors temperature and pH levels via TRICONEX 3721 input modules. If parameters exceed safe limits, it activates isolation valves to halt reactions, preventing chemical spills or explosions.
Nuclear Power: While the TRICONEX 3101S2 is explicitly certified for nuclear 1E-grade applications, the standard TRICONEX 3101 is used in non-safety-critical systems like turbine control, ensuring reliable operation in high-radiation environments.
Water Treatment: The module regulates pump and valve operations in wastewater plants. By analyzing level sensor data, it adjusts flow rates to prevent overflows, ensuring compliance with environmental standards in humid, corrosive settings.
