      What is the ICS Triplex Trusted TMR Processor System? Why can it achieve near-zero downtime in safety-critical applications?

      The ICS Three-Station Trusted TMR Processor System is a high-reliability control platform designed specifically for Safety Instrumented Systems (SIS). It is based on a Triple Modular Redundancy (TMR) architecture, where three independent processors simultaneously execute the same control logic and compare results through a 2/3 voting mechanism to ensure accuracy and fault tolerance.
      The ICS Triple Trusted TMR Processor System is a high-reliability platform designed specifically for Safety Instrumented Systems (SIS). Based on a Triple Modular Redundancy (TMR) architecture, the system employs three independent processors that execute the same logic in parallel, using a 2/3 voting mechanism to determine the output. This design allows the system to tolerate single points of failure and a certain number of failures without interrupting operation. Combined with hardware-implemented fault tolerance (HIFT), a triple-redundant communication bus, and in-circuit hot-swappable modules, the system eliminates single points of failure and meets stringent safety standards such as SIL3, making it ideal for safety-critical industries such as oil and gas, chemical, and power generation.

      • High Integrity Digital Input Design

        The ICS Triplex T8403 is a reliable TMR digital input module designed specifically for Safety Instrumented Systems (SIS). It supports 24VDC input and employs a Triple Module Redundancy (TMR) architecture and a 2/3 voting mechanism to ensure accurate signal processing and fault tolerance, meeting SIL3 safety requirements.

      • Diagnostic and Reliability Features

        The T8403 features built-in diagnostics, fault detection, and hot-swappable capabilities, allowing for maintenance without shutting down the system. With redundant backplane communication, it ensures reliable operation and seamless integration in high-demand industries such as oil and gas and power generation.

      What makes the ICS Triplex Trusted TMR Processor System the "gold standard" for mission-critical security controls?

      The ICS Triplex Trusted TMR processor system is renowned for its Triple Module Redundancy (TMR) architecture, which provides unparalleled reliability. Three processors operate in parallel, employing a 2/3 voting mechanism to verify results, ensuring continuous system operation even if one channel fails. In addition to redundancy, the system integrates hardware-implemented fault tolerance (HIFT) for rapid fault detection and isolation; supports hot-swappable modules for zero-downtime maintenance; and utilizes fully redundant communication paths to eliminate single points of failure. The system is SIL3 certified, meeting stringent international safety standards, while providing high availability, fast response times, and robust diagnostic capabilities. These features make it the "gold standard" solution for industries such as oil and gas, chemicals, and power generation, where zero tolerance for system failures is required.

      Reliable SIL3-Certified ICS Triplex TMR by Moore Automated

      This product has achieved SIL3 (Safety Integrity Level 3) certification according to IEC 61508, ensuring reliable operation even in systems where failure could pose a serious hazard. Furthermore, it complies with various functional safety and reliability standards in industries such as oil and gas, chemicals, and power generation. These certifications confirm that the system's Triple Modular Redundancy (TMR) architecture, 2/3 voting logic, Hardware Hidden Fault Tolerance (HIFT), and diagnostic functions meet stringent international safety and performance requirements.
