The Triconex 8311 is an advanced Main Processor Module (MPM) designed for use in Triconex Triple Modular Redundant (TMR) safety systems. This processor module offers exceptional reliability, fault tolerance, and deterministic performance for mission-critical control environments. Built with robust redundancy, advanced diagnostics, and high-speed execution, the 8311 ensures safe and uninterrupted operations across industries requiring SIL 3 certification.
As part of a distributed, rack-based architecture, the 8311 acts as the brain of the safety controller, managing all logical execution, communications, I/O interaction, and diagnostics. It is often deployed in safety instrumented systems (SIS), emergency shutdown systems (ESD), and process shutdown applications where reliability is paramount.
