Schneider BMXCPS2000 Power Supply Module

Schneider Electric BMXCPS2000 Power Supply Module

Product Introduction

The BMXCPS2000 serves as the primary power source for Modicon X80 racks, converting AC mains voltage into the DC voltages required by processors, I/O modules, and sensors. This power supply module accepts a wide input range of 100 to 240V AC, making it suitable for global deployment without voltage selection switches. It delivers three distinct secondary outputs: 24V DC for sensors, 24V DC for I/O modules and processor, and 3.3V DC for module logic circuits. The BMXCPS2000 incorporates overload, overvoltage, and short-circuit protection to safeguard connected equipment. A convenient reset push button enables cold restart functionality, while status LEDs provide clear visual indication of system health.

Technical Specifications

Input Characteristics

The BMXCPS2000 operates with an AC supply voltage range of 100 to 240V, accommodating nominal voltages from 85 to 264V for tolerance against fluctuations. Network frequency acceptance spans 47 to 63 Hz, covering both 50 and 60 Hz mains supplies. Input current draws 0.31A at 240V and 0.61A at 115V, with apparent power consumption rated at 0.07 kVA. Inrush current peaks at 30A for 120V and 60A for 240V, which should be considered when sizing upstream protection devices. The module includes an internal, non-accessible fuse for primary circuit protection, ensuring safety without user intervention.

Secondary Outputs

The BMXCPS2000 provides three independent secondary outputs to power different segments of the X80 system:

• 24V DC sensor power supply: 10.8W at 0.45A

• 24V DC I/O module and processor power: 16.8W at 0.7A

• 3.3V DC I/O module logic power: 8.3W at 2.5A

These outputs are fully protected against overload, overvoltage, and short-circuit conditions, preventing damage to connected modules during fault events. Maximum power dissipation is 8.5W, ensuring efficient operation within the specified thermal limits.

Protection and Monitoring

Comprehensive protection features make the BMXCPS2000 a reliable choice for critical control systems. The secondary circuits include:

• Overload protection to prevent excessive current draw

• Overvoltage protection safeguarding against output voltage spikes

• Short-circuit protection for fault tolerance

Insulation resistance exceeds 100 MΩ between primary and ground, and between primary and secondary circuits, ensuring safety isolation. Dielectric strength ratings include 1500V between primary and secondary logic/output circuits, 2300V between primary and sensor power supply, and 500V between 24V sensor output and ground. Immunity to microbreaks is rated at 1ms, maintaining operation during brief power interruptions.

Status Indication and Control

The BMXCPS2000 features clear visual diagnostics:

• One green LED indicating rack voltage OK

• One green LED showing sensor voltage OK

• A RESET push button for cold restart functionality

These indicators allow operators to quickly verify power status and perform system resets when necessary.

FAQ

1. Is the BMXCPS2000 compatible with all Modicon X80 backplanes?
No, the BMXCPS2000 is not compatible with BMEXBP..02 backplane models. Please verify your backplane compatibility before installation.

2. What are the three secondary outputs of the BMXCPS2000 used for?
The BMXCPS2000 provides 24V DC for sensor power, 24V DC for I/O modules and processor power, and 3.3V DC for I/O module logic circuits. Each output has dedicated current ratings.

3. How do I perform a cold restart using the BMXCPS2000?
Press the RESET push button located on the front of the module. This initiates a cold restart of the connected system, similar to a power cycle.

4. What happens if the BMXCPS2000 experiences a short circuit on the secondary side?
The BMXCPS2000 includes short-circuit protection on all secondary outputs. The module will limit current and protect itself and connected equipment from damage. After the fault clears, normal operation typically resumes without user intervention.
