Schneider Electric BMXNOM0200 Modicon X80 Serial Link Module — 2× RS485/RS232 Ports, Modbus & Character Mode, 115.2/57.6 kbps, 80 mA at 24V DC, IP20

The Schneider Electric BMXNOM0200 is a serial link communication module in the Modicon X80 family, compatible with Modicon M340 and M580 PACs. It provides two independent serial ports configurable as RS232 and RS485 and supports Modbus RTU/ASCII and character‑mode communications for medium to large process applications.

Features & benefits

• Dual serial ports with independent status LEDs allow flexible connection to RS232 or RS485 field devices and serial Modbus equipment.
• Modicon X80 common platform compatibility reduces spare part variety and simplifies maintenance across M340/M580 systems.
• Low current consumption (80 mA at 24 V DC) and compact IP20 module format minimize rack space and power draw.
• On‑module diagnostics (RUN, ERR, SER COM LEDs) speed commissioning and troubleshooting.

Applications

• Serial device integration and Modbus RTU/ASCII communication for process control, machine automation, I/O concentrators, HMIs and legacy serial equipment in industrial environments.

Installation and service notes

• Power is supplied via the host Modicon rack; do not apply external module power.
• Use appropriate RJ45 cabling and wiring for RS232 and RS485 connections per Schneider Electric wiring guidelines.
• Install in an enclosure appropriate for IP20-rated modules; respect ambient and humidity limits.
• Refer to the product datasheet and user guide for wiring diagrams, baud rate settings, termination and biasing recommendations, and firmware compatibility (BMXNOM0200 firmware V1.60 available).
