Case Study: Solving Power Reliability in a Bottling Plant
A beverage bottling facility faced frequent PLC rack failures due to unstable power. The maintenance team needed a robust power supply module that could handle voltage fluctuations and provide clean power to I/O modules. They chose the Schneider BMXCPS2000 from SpareTechPLC. This module, part of the Modicon X80 range, delivers reliable power with a wide input voltage range of 100…240 V AC, ensuring continuous operation even during brownouts.
Product Overview
The BMXCPS2000 is a power supply module designed for Modicon X80 programmable automation controllers. It converts AC power to multiple DC outputs: 24 V DC for sensors and I/O modules, and 3.3 V DC for logic circuits. With a total secondary power of 20 W, it efficiently powers the processor and I/O modules in a rack. The module features a compact design, weighing only 0.3 kg, and mounts easily on a DIN rail or backplane. Its IP20 rating makes it suitable for installation in control cabinets.

Key Features and Benefits
Wide Input Voltage Range
The BMXCPS2000 accepts 100…240 V AC, with limits from 85…264 V AC. This wide range ensures reliable operation in areas with unstable mains power, reducing downtime.
Multiple Outputs for Flexibility
The module provides three separate power outputs: 24 V DC for sensors (0.45 A), 24 V DC for I/O modules and processor (0.7 A), and 3.3 V DC for logic (2.5 A). This eliminates the need for additional power supplies, saving space and cost.
Robust Protection
Built-in protection includes an internal fuse for the primary circuit and overload, overvoltage, and short-circuit protection for the secondary circuits. This safeguards connected equipment from damage.
Status LEDs for Diagnostics
Two green LEDs indicate rack voltage OK and sensor voltage OK, allowing quick visual verification of power status.
Industry Applications
Bottling and Packaging Lines
In a bottling plant, the BMXCPS2000 powers the Modicon X80 PLC that controls conveyor belts, fillers, and cappers. Its resistance to microbreaks (1 ms) prevents unnecessary shutdowns during brief power interruptions.
Water Treatment Facilities
Water treatment plants often have fluctuating power. The BMXCPS2000’s wide input range and high insulation resistance (>= 100 MOhm) ensure safe and reliable operation in humid environments.
Manufacturing Automation
In automotive assembly lines, the module provides stable power to I/O modules that control robots and sensors. The IP20 rating and vibration resistance (3 gn) make it suitable for industrial environments.
Installation and Setup
The BMXCPS2000 mounts on a Modicon X80 backplane (not compatible with BMEXBP..02). Connect the line supply and protective earth to the 5-pin connector. The 2-pin alarm relay connector can be used for external monitoring. Ensure the module is installed in a control cabinet with adequate ventilation. The operating temperature range is 0…60 °C, so avoid direct heat sources.
Maintenance and Reliability
The BMXCPS2000 requires minimal maintenance. Periodically inspect the module for dust accumulation and ensure connectors are secure. The internal fuse is not accessible; if a fault occurs, replace the module. With a MTBF (not specified) and robust design, it offers long-term reliability. For ROI, consider that preventing downtime in a bottling plant can save thousands of dollars per hour.
Compatibility and Integration
The BMXCPS2000 is compatible with Modicon X80 racks and works seamlessly with other X80 modules. It communicates power status via LEDs. It meets standards EN 61131-2, EN 61000-6-4, EN 61000-6-2, and EN 61010-2-201, ensuring integration into existing systems.
Selection Guide
When selecting a power supply for Modicon X80, verify the backplane compatibility and power requirements. The BMXCPS2000 suits applications needing up to 20 W. For higher power, consider other modules. SpareTechPLC offers the BMXCPS2000 with fast shipping and expert support. Contact us for bulk pricing.
Troubleshooting
