Product Details:

TRICONEX RXM4201 is a multi-mode fiber remote extender module developed for Triconex TMR safety instrumented systems (SIS). This TMR safety module converts Tricon internal I/O bus electrical signals into optical signals, realizing the connection between the main controller rack and remote I/O chassis through multi-mode optical fiber. The module adopts triple modular redundant 2-out-of-3 voting architecture, which can maintain stable signal transmission when one redundant channel fails, eliminating single point failure risk for distributed safety control. It uses multi-mode fiber with ST fiber connectors, the maximum transmission distance reaches 2 kilometers, and the communication rate is 375 kbps. Optical transmission achieves complete galvanic isolation between the main rack and remote rack, effectively resisting strong electromagnetic interference in industrial sites. The module has built-in continuous link diagnosis function, can monitor optical link status in real time, detect signal loss and link abnormal state, and upload fault alarm information to the safety controller. The module supports hot swap operation, maintenance personnel can replace the faulty module online without shutting down the whole safety system, reducing system downtime. It cooperates with Tricon main processor rack, remote I/O chassis and matched multi-mode fiber assemblies. Widely applied in oil & gas, petrochemical, chemical and power industries, this TRICONEX RXM4201 remote extender module undertakes medium-distance safety signal transmission work for ESD emergency shutdown, fire and gas detection and burner management safety interlock systems.
