The Schneider Electric BMXCPS4002 is a rack-mount AC power supply module designed exclusively for the Modicon M340 PLC platform. It is widely deployed across demanding industrial environments where stable, regulated DC bus power is critical to system uptime. Typical application scenarios include:
- Automotive Assembly Lines – Powers M340 CPUs and I/O racks controlling robotic welding cells, conveyor sequencing, and quality inspection stations.
- Water & Wastewater Treatment Plants – Supplies continuous power to M340 controllers managing pump stations, dosing systems, and SCADA-connected RTUs.
- Oil & Gas Upstream/Midstream – Used in wellhead control panels and pipeline SCADA cabinets where wide-range AC input (100–240 VAC) accommodates unstable field power.
- Food & Beverage Processing – Integrated into hygienic-area control panels running CIP sequences, filling lines, and packaging machinery.
- Building Management Systems (BMS) – Provides reliable bus power for M340 controllers managing HVAC, lighting, and energy metering in commercial facilities.
- Pharmaceutical Manufacturing – Supports validated M340 systems in GMP-compliant environments requiring documented, traceable hardware.

Application-Specific FAQ
Q: Can the BMXCPS4002 power a full 12-slot M340 rack with all slots occupied?
A: The BMXCPS4002 provides 40 W to the backplane. For fully loaded 12-slot racks with high-power modules, verify total module power consumption against this budget. For higher-demand configurations, consider the BMXCPS4022 (redundant) or BMXCPS3500 (higher wattage variants).
Q: Is this module compatible with the Modicon M580 platform?
A: No. The BMXCPS4002 is designed exclusively for the Modicon M340 (BMX) rack family. Modicon M580 uses the BMENOC and BMECPS series power supplies.
Q: Does the 24 VDC sensor output support field device power in a panel?
A: Yes, the integrated 24 VDC / 0.5 A output can power proximity sensors, limit switches, and other low-current field devices directly, reducing the need for a separate 24 VDC PSU in small systems.
Q: What happens during an AC input power failure?
A: The BMXCPS4002 provides a brief hold-up time allowing the CPU to execute a controlled shutdown. For extended ride-through, pair with an external UPS system on the AC input.
Q: Can I use this module in a hazardous area (Zone 1 / Class I Div 1)?
A: The BMXCPS4002 is rated IP20 and is not ATEX/IECEx certified for use in hazardous areas. It must be installed in a purged or pressurized enclosure (Ex p) or located in a safe area with appropriate barriers.
