Schneider Electric BMXNOM0200 Digital Input Module

The BMXNOM0200 is Schneider Electric’s two‑channel Modicon X80 serial link module that adds dedicated serial communication to Modicon M580 and M340 PLCs. It provides two configurable RS‑485 or RS‑232 ports for Modbus RTU and Modbus ASCII (character mode) communications, enabling reliable data exchange with remote devices and field instruments over serial links. A front‑panel locking screw secures the module in its rack slot for solid, vibration‑resistant mounting. As part of the Modicon X80 family, the BMXNOM0200 integrates into Schneider Electric’s era of scalable, modular automation platforms and supports firmware updates to maintain compatibility and feature enhancements, with documented revisions such as V1.60. This serial link module is designed to bridge Schneider Electric PLCs with third‑party serial devices, enabling straightforward configuration of master/slave Modbus networks and ASCII‑based communications without occupying additional digital I/O resources.
