Triconex, now part of Schneider Electric, is a globally renowned brand for triple modular redundant (TMR) safety PLC systems. Triconex safety instrumented systems are specially designed for high-risk process industries including oil, gas, petrochemical, chemical and thermal power generation. The core advantage of Triconex products is its TMR triple redundant architecture, which greatly improves system fault tolerance.

In high-risk process plants, the SIS safety system works independently from DCS control system. When dangerous abnormal conditions happen in production process, Triconex SIS system executes safety interlock actions such as shutting down pumps, closing emergency shut-off valves and stopping burners to prevent explosion, leakage and other major safety accidents. Even if one hardware module fails, the other two redundant channels can continue to operate normally to guarantee safety protection function.

The Triconex system is composed of redundant CPU modules, digital input cards, digital output cards, analog input/output modules, communication interface cards and backplane rack chassis. Every hardware module adopts high-reliability industrial components and strict industrial-grade design, to adapt to complex factory environment.

We supply original Triconex redundant modules, CPU cards, digital input/output modules, communication cards and backplane racks. All these safety control components have high reliability and fault-tolerant performance, meeting international SIL safety standards. Triconex spare parts are critical resources for safety system maintenance, spare parts backup and system upgrade of petrochemical plants and power stations.
