The TriconeX 5211S2 processor is a high-performance, triple redundant central processing unit (CPU) module produced by TriconeX, belonging to the Tricon family ®  The core component of Safety Instrumented System (SIS) has high reliability, powerful processing capabilities, and comprehensive self diagnostic functions.

Core Features

Triple Modular Redundancy (TMR) Architecture

Three independent 5211S2 CPUs execute logic in parallel and perform continuous cross comparisons through high-speed TriBus.

Adopting a "2-out-of-3" voting mechanism to ensure fault tolerance and compliance with SIL3 application certification standards.

Even if a single CPU fails, the system can still maintain operation through redundant components, and the faulty module can be replaced online during maintenance without shutting down.

Powerful processing capability

Equipped with high-performance processors and sufficient memory, it supports efficient execution of complex control logic and safety interlock programs.

Supports Triconex's proprietary TriStation 1131 programming software, compatible with multiple languages of IEC 61131-3 standard (such as ladder diagram LD, functional block diagram FBD, structured text ST).

Comprehensive self diagnostic function

Real time monitoring of key components such as CPU, memory, clock, power supply, TriBus communication, etc.

Abnormal situations are clearly reported through the front panel LED indicator lights and TriStation software, making it easy to quickly locate and solve problems.

Durable industrial design

Adopting industrial grade components and strict manufacturing processes, it adapts to harsh electromagnetic environments, wide temperature ranges (-20 ° C to+70 ° C), and vibration conditions.
