Schneider Electric BMXP342000 Modicon M340 Processor 1024 DI 256 AI Modbus Programmable Logic Controller

The Schneider Electric BMXP342000 is a Modicon M340 processor module (Modbus concept) supporting up to 4 racks, 1024 discrete and 256 analog I/O points, with integrated RS232C/RS485 serial ports, a USB port, and capacity for 2 Ethernet or 4 AS-Interface communication modules. It ships with a BMXRMS008MP memory card for program, constant, symbol and data backup.

Selection Notes

With Modbus as its only fieldbus concept, the BMXP342000 suits M340 applications that standardize on Modbus RTU/ASCII over the integrated RS232C/RS485 ports rather than needing a CANopen motion bus - choose the BMXP3420102 instead if the machine needs CANopen slave devices or independent-axis motion control. Its 4-rack, 1024 discrete / 256 analog I/O capacity covers most process and machine-control architectures without a separate remote I/O processor, and its 72 mA current draw at 24 V DC keeps the rack power-supply budget modest even in a fully populated 4-rack system.
