Schneider Electric 140CPS21400 Modicon Quantum Power Supply Module

Product Description

The Schneider Electric 140CPS21400, also cataloged as the 140CPS21400 power supply module, operates as a dedicated hardware component for 24 VDC power distribution within Modicon Quantum automation platform systems.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The module interfaces directly with the Modicon Quantum backplane bus architecture, ensuring deterministic power distribution and voltage regulation for high-density I/O configurations. Firmware flash compatibility supports standard runtime updates across compatible CPU and communication processor modules. Backplane communication velocity relies on stable 5.1 VDC bus provisioning, where summable output configurations (up to 8 A) maintain bus integrity under variable load conditions without introducing propagation delays or communication jitter.

Frequently Asked Questions

Q: What are the restrictions regarding the summable power supply configuration on the Quantum backplane?

A: Summable power supplies allow parallel configuration to increase total available output current for the 5.1 VDC backplane rail, provided total load requirements and physical thermal dissipation limits within the Quantum rack are respected.

Q: How does the module handle input power interruptions?

A: The internal circuitry provides power interruption ride-through of up to 100 ms (or 1 ms at 20 VDC input), preventing unintended processor resets or system faults during brief line dips.

Field Installation Guidelines

Ensure the Quantum rack is securely mounted on a grounded surface before module insertion. Verify that incoming 24 VDC supply lines are protected via an external 5 A slow-blow fuse. Check shielding and grounding connections for electromagnetic compatibility (EMC), adhering to industrial standards for electrostatic discharge and electromagnetic field resistance in control cabinet environments.
