Schneider BMXNOM0200H Modicon X80 2-Port Serial Module

Schneider Electric BMXNOM0200H Modicon X80 Serial Communication Module

The Schneider Electric BMXNOM0200H is a ruggedized serial communication module designed for the Modicon X80 automation platform. It adds two independent serial channels to Modicon M340 and M580 PLC systems, enabling direct data exchange with field devices such as variable frequency drives, power meters, sensors, and remote terminal units (RTUs).

Communication Interfaces and Protocol Support

The module features two RJ45 serial ports that support configurable RS-232 and RS-485 physical interfaces. Channel configurations accommodate 8-wire RS-232 connections operating at data rates up to 115.2 kbit/s and 1-twisted-pair RS-485 connections operating up to 57.6 kbit/s. Supported transmission modes include Modbus Master/Slave (RTU and ASCII formats), Character mode communication, and GSM/GPRS modem connectivity.

Environmental Resistance and Diagnostics

Designed for severe industrial environments, the BMXNOM0200H incorporates conformal coating on internal circuitry to resist dust, high humidity, salt mist, and corrosive gas exposure. It operates reliably across an extended temperature range of -25 to +70 deg C. Front-panel LEDs provide local status diagnostics for module health (ERR, RUN) and individual port communication activity (SER COM 0, SER COM 1).
