TRICONEX 3101S2 TMR Main Processor Module
Product Overview
The TRICONEX 3101S2 is a Triple Modular Redundancy (TMR) main processor module designed as the core of TRICONEX’s safety instrumented systems (SIS), specifically engineered for mission-critical industrial applications. Serving as the central processing unit, this module executes safety logic, coordinates data exchange between I/O modules (e.g., TRICONEX 2101, 2301), and ensures fault-tolerant operation in high-risk environments such as oil refineries, chemical plants, and power generation facilities.
Built on TRICONEX’s proven TMR architecture, the 3101S2 integrates three independent processors that operate in parallel, continuously cross-validating results to eliminate single points of failure. This redundancy ensures seamless operation even if one processor fails, a critical feature for applications where downtime could lead to environmental hazards or financial losses. The module supports real-time data processing, with a 333 MHz clock speed and 256 MB RAM, enabling rapid execution of complex safety algorithms in scenarios like emergency shutdown (ESD) systems or high-integrity pressure protection systems (HIPPS).
Certified to SIL 3 (IEC 61508), the 3101S2 meets the highest safety standards, ensuring compliance with regulatory requirements in industries like nuclear power and offshore oil production. Its rugged design includes conformal coating to resist dust, moisture, and chemical exposure, allowing reliable operation in temperatures ranging from -40°C to 70°C and humidity up to 95% (non-condensing). While a mature model, the 3101S2 remains widely used due to its backward compatibility with legacy I/O modules and support for modern field devices, minimizing the need for costly system overhauls.

Main features and advantages
Triple Modular Redundancy (TMR): The 3101S2 uses three identical processors to independently execute safety logic. A voting circuit selects the majority outcome, ensuring operation continues even if one processor fails. This redundancy is critical in offshore oil platforms, where a single processor failure could delay emergency shutdowns during leaks.
SIL 3 certification: Certified to IEC 61508 SIL 3, the module meets the highest safety standards, making it suitable for applications like chemical reactor control, where reliable processing is essential to prevent explosions or toxic releases.
High processing power: With a 333 MHz clock speed and 256 MB RAM, the 3101S2 handles real-time data from dozens of I/O modules. In coal-fired power plants, this speed allows it to adjust turbine operations within milliseconds to prevent overspeed.
Broad compatibility: The module works seamlessly with all Tricon I/O modules (e.g., 2101, 2301), communication modules, and termination boards, reducing upgrade costs by allowing users to retain legacy I/O while enhancing processing capabilities.
Rugged industrial design: The 3101S2 operates in extreme temperatures (-40°C to 70°C) and resists humidity, dust, and chemical exposure. Its conformal coating protects against corrosive gases in chemical plants, ensuring a service life of 10+ years in harsh environments.
Hot-swappable capability: The module can be replaced while the system runs, enabling maintenance without shutting down critical processes. In natural gas processing plants, this feature saves thousands in downtime costs during scheduled maintenance.

Installation and maintenance
Pre-installation preparations: Verify the 3101S2 is compatible with your Tricon rack (e.g., Tricon 6000) and that the power supply (e.g., 9662) provides 24 V DC ±10%. Power off the system and disconnect all power sources. Align the module with the dedicated processor slot in the rack, secure it with screws, and connect the backplane data cable. Ground the module using the dedicated terminal to reduce electrical noise.
Maintenance suggestions: Inspect the 3101S2 monthly. Use compressed air to clean dust from vents to prevent overheating. Check status LEDs: solid green indicates normal operation, while flashing red signals a processor fault. Use Tricon’s TriStation software to run diagnostic tests and identify failing processors. Store a spare 3101S2 in a dry, cool area (10–30°C) for quick replacement during failures, minimizing downtime.
Application fields
The TRICONEX 3101S2 is widely used in industries where safety-critical processing is non-negotiable:
- Oil and gas: In onshore refineries, the 3101S2 acts as the ESD system’s core, processing input from 2101 modules monitoring pipeline pressure. It triggers valve closures within 50 milliseconds if pressure spikes 10% above safe limits, leveraging TMR redundancy to ensure logic execution even if one processor fails.
- Chemical processing: In fertilizer plants, the module monitors 20+ analog and digital inputs (e.g., reactor temperature, agitator speed) from I/O modules. It maintains pH levels within a 0.2 range by activating 2301 modules to adjust chemical dosing pumps, preventing explosive byproducts.
- Power generation: In nuclear power plants, the 3101S2 controls reactor protection systems. It processes neutron flux, coolant flow, and pressure data, triggering emergency shutdowns if readings exceed thresholds, ensuring compliance with nuclear safety regulations.
- Water treatment: In municipal wastewater plants, the module coordinates pump operations and chemical dosing using flow meter data. Its redundant processing ensures continuous adjustments to prevent tank overflow while minimizing energy use.
