Schneider BMXNOM0200 Modicon X80 Serial Link Communication Module 2 Ports

Schneider Electric BMXNOM0200 is a serial communication module for Modicon X80 automation systems. Provides two configurable RS485 or RS232 ports supporting Modbus and character mode protocols. Used in Modicon M340 and M580 PAC racks for connecting serial devices such as drives, HMIs, barcode readers, and instrumentation.

Applications:

• Serial communication with Modbus RTU devices

• Connection to legacy RS232/RS485 field instruments

• Data exchange between Modicon X80 and third‑party serial equipment

• Redundant or multi‑drop serial network configurations
