TRICONEX 4210 Primary SRXM Single-Mode Fiber Remote Extender Module for Tricon SIS

Product Description

The TRICONEX 4210 is a high-integrity Primary Single-Mode Fiber Remote Extender Module (SRXM), engineered by TRICONEX (Schneider Electric) for Tricon safety instrumented systems (SIS). As a TMR (Triple Modular Redundant) set of 3 modules, it enables reliable extension of I/O points to remote locations via single-mode fiber-optic links, reducing wiring complexity and enabling monitoring/control of field devices far from the main controller. This hot-swappable module supports up to 3 remote sites, 12 km (7.5 miles) maximum fiber distance, and features comprehensive LED diagnostics—making it ideal for critical ESD, F&G, and process safety applications in oil & gas, chemical, petrochemical, and power generation industries.

Key Functions

The 4210 SRXM delivers fault-tolerant remote I/O extension for Tricon SIS, leveraging TMR architecture and single-mode fiber for high reliability. Key functions include: acting as the primary RXM in the main chassis to communicate with remote RXM chassis; supporting up to 3 remote sites with 6 ST fiber connectors per site; enabling 12 km (7.5 miles) maximum fiber distance for each remote link; providing TMR voting for data integrity and fault tolerance; 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 I/O modules.

Application Scenarios

The TRICONEX 4210 SRXM is deployed in safety-critical industrial applications requiring 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.
