Core Features & Customer Value

Triple Modular Redundancy Architecture: The T8191’s TMR design incorporates three independent processing channels that execute identical operations and vote on outputs. For engineering teams responsible for safety system design, this architecture provides maximum fault tolerance that prevents single component failures from causing dangerous system states. The voting logic automatically masks faulty signals from the remaining healthy channels, maintaining control system integrity while alerting operators to the need for maintenance. This capability ensures that the system can continue operating safely even with a failed component, allowing maintenance to be scheduled during planned shutdowns rather than causing unplanned production interruptions.

High-Performance Processing: The module’s 100 MHz processor clock and triple redundant architecture deliver the computational power required for complex safety logic and real-time control applications. For system integrators, this processing capability enables the implementation of sophisticated safety functions without compromising response times. The module can handle multiple safety instrumented functions simultaneously while maintaining the fast response times required for critical shutdown applications. The triple redundant processing ensures that computational errors are detected and corrected in real-time, maintaining system integrity even during transient conditions or electromagnetic interference events.

Comprehensive Diagnostic Coverage: The processor performs continuous self-monitoring of all critical components, including processing cores, memory, power supplies, and communication interfaces. This diagnostic capability provides early detection of potential failures before they affect system operation. For maintenance personnel, the detailed fault reporting through front-panel indicators and system software reduces troubleshooting time and enables targeted component replacement. The system can detect and report various fault conditions, including processor faults, memory errors, communication failures, and power supply issues, allowing technicians to quickly identify and resolve issues before they affect system operation.

Hot-Swap Capability: The module supports hot-swap replacement when used in a properly configured Trusted TMR system. This feature allows the processor to be replaced while the system remains powered and operational, minimizing production impact during maintenance activities. The system automatically detects the new module and synchronizes it with the existing configuration, reducing commissioning time and potential for human error. For plant operators, this capability translates to reduced downtime and improved system availability, as maintenance can be performed without taking the entire safety system offline.

Typical Applications

The ICS Triplex T8191 is extensively deployed in safety-critical process control applications within hydrocarbon processing facilities. In emergency shutdown systems (ESD), the processor module typically executes safety logic that monitors critical process variables and initiates shutdown commands when predefined trip conditions are met. The module’s fast response time and SIL 3 certification ensure that safety functions are executed within the required safety time constraints, protecting personnel, equipment, and the environment.

In fire and gas detection systems, the T8191 processes signals from fire detectors, gas detectors, and manual call points, activating fire suppression systems, emergency ventilation dampers, and alarm systems. The processor’s high reliability and fault tolerance ensure that safety functions remain operational even during component failures, meeting the high availability requirements of life safety systems. The comprehensive diagnostic capabilities provide early warning of developing issues that could affect system reliability.

For power generation applications, particularly in turbine control systems, the T8191 provides control functions for anti-surge valves and fuel gas shutdown valves. The wide operating temperature range (0°C to 60°C) allows deployment in unmanned compressor stations where environmental control may be limited. The processor’s robust construction and high immunity to electrical noise ensure reliable operation in the electrically noisy environments typical of power generation facilities.
