Buyer’s Guide to the Schneider BMXCPS2000 Power Supply Module
The Schneider BMXCPS2000 is a power supply module from the Modicon X80 range. It converts a 100…240 V AC supply into the regulated DC rails that X80 I/O modules and processors need. If you are replacing a failed supply or building a new X80 rack, this guide walks through the specs, fit, and practical checks before you buy.
What This Module Actually Delivers
The BMXCPS2000 splits its 20 W secondary output across three DC rails. The 24 V DC sensor power supply provides 10.8 W and 0.45 A. The 24 V DC I/O module power supply and processor section provides 16.8 W and 0.7 A. The 3.3 V DC I/O module logic power supply provides 8.3 W and 2.5 A. That split matters because sensor loads, I/O modules, and logic circuits each draw from a dedicated rail instead of competing for one shared output.

Reading the Input and Output Ratings
The wide input window from 85…264 V means the module tolerates the voltage sag and swell that commonly appear on industrial AC feeds. The network frequency limits of 47…63 Hz cover both 50 Hz and 60 Hz grids, so the same part works across regions. Input current stays modest at 0.31 A on 240 V, which keeps upstream breaker and wiring sizing simple. On the output side, the three DC rails give you a predictable budget for sensors, I/O, and logic without adding a separate 24 V supply.
Protection and Status Monitoring
The primary circuit carries an internal fuse that is not accessible to the user. The secondary circuit includes overload, overvoltage, and short-circuit protection. Two green LEDs sit on the front: one confirms rack voltage OK, and one confirms sensor voltage. During commissioning, these LEDs let you verify power without a meter. The RESET push-button supports a cold restart when you need to cycle the module.
Where the BMXCPS2000 Fits
This module suits Modicon X80 racks in process control cabinets, machine control panels, and remote I/O enclosures. It is not compatible with BMEXBP..02 backplanes, so confirm your backplane part number before ordering. Because the module is IP20, mount it inside a protected enclosure away from dust and moisture. The 0…60 °C operating range covers most climate-controlled plant rooms, while the -40…85 °C storage range supports spare-parts inventory in unheated warehouses.
Installation and Setup Notes
Electrical connection uses a 5-pin connector for line supply, protective earth, and the 24 V DC sensor input, plus a 2-pin connector for the alarm relay. Wire the protective earth first, then line supply, then sensor input. Keep the module vertical in the rack so convection cooling works. The 8.5 W maximum power dissipation is low, but leave clearance around the rack for airflow. After power-up, check both green LEDs and confirm the alarm relay behaves as expected.
Maintenance and Reliability
Inspect the module periodically for loose connectors, discoloration, or dust buildup on the enclosure. Because the primary fuse is internal and not accessible, a blown primary fuse means the module must be replaced rather than repaired. Keep spares on hand if the rack supports a critical process. Store spares within the -40…85 °C range and keep humidity between 5…95 % at 55 °C without condensation. The module meets EN 61131-2, EN 61000-6-4, EN 61000-6-2, and EN 61010-2-201, and carries UL, CSA, CE, RCM, EAC, and Merchant Navy certifications.
Compatibility Checks Before You Buy
Confirm three things: your backplane is not a BMEXBP..02, your supply is within 100…240 V AC, and your load stays inside the three DC rail budgets. The module also handles 1 ms microbreaks and 3 gn vibration, so it suits machinery with moderate shock and vibration. If you need a replacement or a spare, SpareTechPLC stocks industrial automation parts and can confirm availability.
Frequently Asked Questions
Is the BMXCPS2000 compatible with all Modicon X80 backplanes?
No. It is not compatible with BMEXBP..02 backplanes. Verify your backplane part number before ordering.
What output rails does this module provide?
It provides 24 V DC sensor power, 24 V DC I/O and processor power, and 3.3 V DC logic power.
Can I replace the internal fuse?
No. The primary fuse is internal and not accessible. A failed primary fuse requires module replacement.
What is the operating temperature range?
The module operates from 0…60 °C and stores from -40…85 °C.
Does it support both 50 Hz and 60 Hz networks?
Yes. The network frequency limits are 47…63 Hz, covering both 50 Hz and 60 Hz supplies.
