Product Introduction
The Schneider Electric BMXP3420302 is a high-performance processor module within the Modicon M340 Programmable Automation Controller (PAC) family. Built for critical automation applications, this CPU offers a substantial memory footprint, fast instruction execution, and robust multitasking capabilities. It is designed to meet the needs of complex control systems in sectors such as manufacturing, energy, water treatment, and transportation.
With 3 MB of user memory, support for 64 simultaneous tasks, and efficient Boolean logic execution, the BMXP3420302 provides the processing backbone for scalable, high-reliability industrial control architectures. Equipped with USB and serial ports, and compatible with multiple communication modules, it integrates easily into Modbus-based and Ethernet-based networks.
Its DIN-rail mountable compact design allows for efficient panel space utilization, while its advanced diagnostics, compatibility with EcoStruxure Control Expert (formerly Unity Pro), and modular expandability make it a future-proof choice for smart automation systems.
