It draws 80 mA at 24 V DC from the rack backplane and provides two independent RJ45 serial ports: one RS232 at 115.2 kbit/s and one RS485 at 57.6 kbit/s. The module carries CE marking, complies with IEC 61131-2, UL 61010-2-201, CSA C22.2 No 61010-2-201, and ATEX directives 2014/34/EU. Its IP20 enclosure and conformal coating suit installation in panels subject to vibration, humidity, gas, dust, sand, salt, and fungal exposure. ## How it compares to BMXNOR0200H BMXNOR0200H is a communication module for the Modicon M340 platform with an Ethernet port and a single RS232/485 serial port. BMXNOM0200H belongs to the X80 rack family and has two dedicated serial ports, an RS232 and an RS485, but no Ethernet. The two modules are not physically or electrically interchangeable — they serve different backplanes (X80 vs. M340) and different topology requirements. ## Integration notes Mounts in any X80 standard-format slot. Power and bus communication come through the rack backplane; no external supply needed. The two RJ45 ports are labeled SER COM 0 and SER COM 1 with independent green activity LEDs. Module fault (ERR) and run (RUN) LEDs are red and green respectively. Strip the serial cable ends per the connector manufacturer's recommendation for RS485 termination and biasing; the module does not provide built-in line termination.","metaTitle":"BMXNOM0200H Modicon X80 Serial Links Module - Harsh Environm","metaDescription":"BMXNOM0200H is an active Modicon X80 serial module for severe environments.
