TRICONEX 8110 TMR Safety Controller (Tricon CX System Core) for SIL 3 Safety Instrumented Systems (SIS)

Product Description

The TRICONEX 8110 is the high-integrity Triple Modular Redundant (TMR) safety controller, serving as the core processing unit of the TRICONEX Tricon CX safety instrumented system (SIS). Engineered to meet IEC 61508 SIL 3 certification, it delivers fault-tolerant, deterministic control for mission-critical safety interlocks, emergency shutdown (ESD), fire & gas (F&G), and turbine/generator protection systems in hazardous industrial environments. The 8110 features three identical and independent processing channels that execute the same safety logic in parallel, with majority voting to eliminate single points of failure. It supports hot-swappable module maintenance, redundant power inputs, and seamless integration with TRICONEX I/O modules (digital, analog, supervised output) and communication modules, while advanced self-diagnostics continuously monitor hardware health, voting integrity, and system status to ensure compliance with strict safety standards.

Key Functions

The TRICONEX 8110 controller executes safety instrumented functions (SIFs) with TMR fault tolerance, ensuring safe operation even if one processing channel fails. It processes input signals from field sensors/switches, executes user-defined safety logic (ladder diagrams, function block diagrams), and outputs control commands to actuators (valves, pumps, alarms) via I/O modules. The TMR architecture with majority voting (2-out-of-3) guarantees that a single-channel fault does not affect system output, while redundant power supplies and hot-swappable modules maximize system availability. The controller supports online configuration changes and downloads without system shutdown, and built-in diagnostics provide real-time monitoring of CPU health, memory status, I/O communication, and voting errors, enabling proactive maintenance and reducing downtime. It also integrates with TRICONEX engineering tools (TriStation 1131) for intuitive safety logic development, testing, and commissioning.

Application Scenarios

The TRICONEX 8110 TMR safety controller is deployed in safety-critical applications across oil & gas, chemical, petrochemical, power generation, and other high-risk industries. In offshore platforms and refineries, it serves as the core of ESD and F&G systems, processing signals from pressure/temperature switches, gas detectors, and emergency stop buttons to trigger valve closures and shutdown sequences. In chemical plants, it controls reactor safety interlocks, toxic gas leak mitigation, and emergency vent systems to prevent explosions and chemical releases. In power plants (thermal, nuclear, wind, solar), it monitors turbine vibration, boiler water level, and generator overcurrent conditions to actuate emergency stop systems and protect critical equipment. The controller is also used in pharmaceutical manufacturing for batch process safety, mining operations for hoist/conveyor protection, and water/wastewater treatment plants for chemical dosing safety—all scenarios where system failure could result in human harm, environmental damage, or catastrophic financial loss.
