Product Description

The BMXCPS4002 is a high-performance AC power supply module developed by Schneider Electric for the Modicon M340 and M580 Platforms. This module provides regulated electrical power to the PLC backplane, supplying the DC voltages required by processors, communication modules, and I/O interfaces.

Designed for industrial reliability, the BMXCPS4002 converts a wide range of AC input voltages into stable DC outputs while protecting the system against electrical disturbances such as voltage spikes, overloads, and short circuits. Its compact design helps reduce heat accumulation inside control cabinets while maintaining high energy efficiency.

Application

The BMXCPS4002 is commonly used in:

  • Water and wastewater treatment automation

  • Packaging and material handling systems

  • Industrial manufacturing control panels

  • Infrastructure monitoring and process control systems

It is particularly useful in regions with unstable power grids due to its wide input voltage tolerance, helping maintain continuous PLC operation during minor voltage fluctuations.

Technical FAQ

Does the BMXCPS4002 support battery backup?
Yes. The module supports a backup battery (such as TSXBATCCG) to preserve CPU RAM and real-time clock data during power outages.

What is the purpose of the “Volt Free” contact?
The dry contact relay closes when power is operating normally. It can be wired to PLC inputs or external alarm systems to signal power supply failure immediately.
