Invensys TRICONEX 4200 Remote Extender Module (RXM)

Description

The Invensys TRICONEX 4200 Remote Extender Module (RXM) is a high-performance remote expansion component designed for industrial automation and safety-critical applications, as part of the Triconex safety instrumented system (SIS). Its core function is to extend the I/O capacity of Triconex systems, enabling placement of I/O modules far from main control rooms to simplify on-site equipment monitoring and maintenance. It supports multiple communication protocols including RS-485, Ethernet, PROFIBUS, Profibus DP, and Modbus TCP/IP, with fiber optic transmission options offering a maximum communication rate of 375 kilobits per second and extended distances up to 12 kilometers, or 1000 meters for standard configurations.

Key technical specifications include a 24VDC power supply, DIN rail installation, operating temperature range of -40 degrees Celsius to 70 degrees Celsius, and optional protection ratings of IP20, IP65, or IP66 for dust and water resistance. Measuring 190mm x 60mm x 35mm and weighing approximately 0.5 kg, the module features a modular design, redundant functionality, and compliance with the IEC 61508 SIL3 safety standard. Built to withstand harsh industrial environments, it is ideal for use in oil and gas, chemical, power, and nuclear industries, working in conjunction with other Triconex modules to boost system reliability and flexibility.
