Product Overview
The Triconex 3351S2 is a high-integrity Triple Modular Redundant (TMR) controller module designed for mission-critical safety applications. As part of Triconex’s renowned TriStation 1131 platform, this safety-certified controller provides fault-tolerant control for emergency shutdown systems (ESD), fire and gas systems, and turbine control. The 3351S2 leverages three independent 32-bit processors operating in parallel, delivering SIL 3-certified performance per IEC 61508 standards.
Engineered for continuous operation in harsh industrial environments, the Triconex 3351S2 features automatic fault detection and correction mechanisms. Its modular architecture supports hot-swappable components, enabling online maintenance without process interruption. The controller integrates seamlessly with Triconex’s I/O subsystems and supports multiple communication protocols including Modbus TCP/IP and OPC UA, making it a cornerstone of modern distributed control architectures.
