Schneider BMXNOM0200 Communication Module, Modicon X80, Serial link module, 2 RS

The Schneider Electric BMXNOM0200 is a serial communication module for the Modicon X80 platform, offering two independent RS-485/RS-232 serial ports that support Modbus and Character mode protocols. Powered internally via the rack, it delivers serial connectivity at up to 115.2 kbit/s on RS232 and 57.6 kbit/s on RS485, making it well-suited for integrating third-party serial devices into Modicon X80 PLC systems.
