TRICONEX 4200 Multimode Fiber Primary Remote Extender Module (RXM) for Tricon SIL 3 SIS

Product Description

The TRICONEX 4200 is a high-integrity Triple Modular Redundant (TMR) multimode fiber primary remote extender module (RXM), engineered by TRICONEX (Schneider Electric) for SIL 3 safety instrumented systems (SIS) in critical industrial environments. Supplied as a TMR set of 3 hot-swappable modules, it acts as the main-chassis primary interface to extend I/O points to remote locations via multimode fiber-optic links—reducing copper wiring costs, eliminating ground loops, and enabling monitoring/control of field devices up to 2 km (1.2 miles) away. With support for up to 3 remote sites, 6 ST connectors per site, and comprehensive LED diagnostics, it is ideal for ESD, fire & gas (F&G), and process safety applications in oil & gas, chemical, petrochemical, and power generation industries.

Key Functions

The 4200 primary RXM enables fault-tolerant, TMR-voted data exchange between the Tricon main chassis and remote I/O chassis, supporting safety-critical and non-safety process data. Key functions include: serving as the primary fiber interface in the main chassis; supporting up to 3 remote sites with 6 ST multimode fiber connectors per site; enabling 2 km (1.2 miles) maximum multimode fiber distance per link; implementing 2-out-of-3 majority voting for data integrity; hot-swappable design for online maintenance without system shutdown; LED status indicators (PASS/FAIL/ACTIVE/TX/RX1/RX2/RX3) for real-time health and communication monitoring; and seamless integration with Tricon main/expansion chassis and 4201 remote RXM modules.

Application Scenarios

The TRICONEX 4200 primary RXM is deployed in safety-critical industrial applications requiring multimode fiber remote I/O extension with SIL 3 compliance. In offshore platforms and refineries, it extends ESD and F&G system I/O to remote wellheads, processing units, and emergency shutdown valves, reducing long-distance copper wiring and enhancing system reliability. In chemical plants, it connects reactor safety interlocks and toxic gas mitigation systems to remote sensor/actuator networks, maintaining SIL 3 safety integrity. In power generation facilities, it links turbine/generator protection systems to remote vibration, temperature, and pressure sensors, enabling real-time condition monitoring and protection. It is also used in mining, pharmaceutical manufacturing, and water/wastewater treatment—all scenarios where remote I/O extension and high availability are critical to preventing safety incidents.
