The BMXP342020 is a high-performance processor module from Schneider Electric's Modicon M340 Programmable Automation Controller (PAC) platform. Designed for demanding industrial automation applications, this module supports up to 1024 discrete I/O (704 in single-rack, 1024 in multi-rack configuration) and 256 analog I/O (66 in single-rack, 256 in multi-rack configuration). It features integrated Modbus serial communication (RS-232C/RS-485) and Ethernet Modbus/TCP connectivity via RJ45 connectors, plus a USB mini-B port for programming. The processor includes 4096 kB total internal RAM (3584 kB for program, constants, symbols; 256 kB for data) and comes with an SD flash memory card (BMXRMS008MP) for automatic backup. With support for up to 4 racks, 11 slots, and 36 application-specific channels, it delivers robust control and monitoring capabilities including diagnostic and event counters. The module operates across 0-60°C and is certified to IEC 61131-2, UL, CSA, CE, and multiple industry standards.
