Schneider Electric BMXCPS3500 24VDC Power Supply Module – Modicon M340 Automation Platform
Imagine a critical production line — an automotive stamping press, a pharmaceutical batch reactor, or a water treatment SCADA node — suddenly losing its PLC power supply. Within milliseconds, the entire control rack goes dark: I/O modules lose state, communication buses drop, and the CPU cannot execute a single scan cycle. Without a reliable, correctly-rated power supply module, even the most sophisticated Modicon M340 configuration is nothing more than inert hardware. The Schneider Electric BMXCPS3500 exists precisely to prevent that scenario, delivering stable, conditioned 24 VDC power to every module on the backplane so your automation system never misses a beat.
Within the Modicon M340 family — Schneider Electric’s mid-range PLC platform trusted across more than 140 countries — the BMXCPS3500 occupies the role of the primary 24 VDC backplane power supply. It is engineered to power the full complement of M340 I/O and communication modules in demanding industrial environments, making it one of the most widely specified power supply references in the Modicon ecosystem. Procurement engineers across process, discrete, and hybrid manufacturing sectors rely on this module as a direct, catalog-verified replacement or expansion component.
