The TRICONEX 3311S21 is a key module in the Triconex safety control system that provides a three-mode redundancy structure (TMR) with three identical subcircuits, each performing an independent degree of control. This design ensures that the system can maintain high reliability and safety in the face of various fault conditions. In addition, the module has a dedicated hardware/software architecture for “voting” on inputs and outputs, further enhancing the fault tolerance of the system.

The module can withstand harsh industrial environments and is suitable for the production process of petrochemical, electric power, pharmaceutical and other industries to ensure the safety and stability of the system. The introduction of the TRICONEX 3311S21 module further enricues the Triconex TNS family of products, which includes a variety of safety redundant controllers, I/O modules, networking equipment and software for building safety-critical control systems.

With the continuous progress of industrial automation technology, the launch of the TRICONEX 3311S21 module will undoubtedly bring a safer and more efficient operation experience to the industrial control system, and further promote the development of Industry 4.0. The launch of this module not only demonstrates Triconex’s technical strength in the field of safety control systems, but also provides a reliable choice for the global industrial automation market.
