Schneider Electric BMXNOM0200 Communication Module

The BMXNOM0200 Serial Link Module from Schneider Electric is a two-port communications card for the Modicon X80 I/O platform, adding serial connectivity to a Modicon X80 rack. It provides two RS-485/RS-232 ports that can operate in Modbus mode or ASCII (character) mode, enabling direct communication with a wide range of serial devices and equipment. The module is designed to plug into the Modicon X80 backplane and to integrate with the rest of the X80 I/O family, sharing the same network and power framework as other X80 modules. In an X80 rack, up to two BMXNOM0200 modules can be installed to expand serial connectivity without consuming additional I/O slots. Typical applications include linking PLCs with remote telemetry units, SCADA systems, HMIs, or other field devices that support Modbus or ASCII over RS-232/RS-485, with support for both master and slave configurations depending on the device role. This module enables reliable industrial serial communication within Schneider Electric’s Modicon X80 ecosystem, delivering a dedicated, plug-in solution for integrating legacy or remote devices into modern control architectures.
