Understanding the Schneider BMXCPS2000 Power Supply Module
The Schneider BMXCPS2000 is a dedicated power supply module for the Modicon X80 automation platform. It accepts a wide AC input range from 100 to 240 V and delivers multiple stable DC outputs to power sensors, I/O modules, and the processor. Engineers rely on this unit for its robust protection features and reliable performance in industrial environments.
Input Characteristics and Efficiency
This module operates on a primary voltage of 100...240 V AC with a frequency of 50/60 Hz. The input current ranges from 0.31 A at 240 V to 0.61 A at 115 V. It also handles inrush currents up to 60 A at 240 V, ensuring safe startup. The apparent power consumption is only 0.07 kVA, making it energy-efficient for continuous operation.
Multiple DC Outputs for System Components
The Schneider BMXCPS2000 provides three distinct secondary power rails. It delivers 10.8 W for 24 V DC sensor supplies, 16.8 W for 24 V DC I/O module and processor power, and 8.3 W for 3.3 V DC I/O module logic. Each output has dedicated current ratings: 0.45 A for sensors, 0.7 A for I/Os and processor, and 2.5 A for logic. This separation ensures clean power distribution and reduces cross-interference.
Protection and Reliability Features
Protection is critical for any power supply. The BMXCPS2000 includes overload, overvoltage, and short-circuit protection on all secondary circuits. The primary circuit has an internal, non-accessible fuse. Additionally, it offers 1500 V dielectric strength between primary and secondary rails, and 500 V between the 24 V sensor output and ground. These specs meet EN 61131-2 and other international standards.
Diagnostics and Control
Two green LEDs indicate rack voltage and sensor voltage status. A RESET push-button enables a cold restart, simplifying troubleshooting. The module also includes an alarm relay connection via a 2-pin connector. For wiring, it uses a 5-pin connector for line supply, protective earth, and 24 V DC sensor input.
Environmental and Mounting Considerations
The unit operates in ambient temperatures from 0 to 60 °C and stores from -40 to 85 °C. It withstands vibrations up to 3 gn and shocks up to 30 gn, with an IP20 rating. The insulation resistance exceeds 100 MΩ between primary and ground. For optimal performance, mount it in a clean, dry cabinet and ensure proper grounding.
By understanding these technical specifications, engineers can integrate the Schneider BMXCPS2000 effectively into their Modicon X80 systems, achieving reliable power delivery and system uptime.
