Schneider Electric 140CPS22424 Quantum Redundant Power Supply

Product Description

The Schneider Electric 140CPS22424 is a redundant DC power supply module developed for the Modicon Quantum automation platform. It is designed to provide a regulated 5.1 VDC output to the PLC backplane from a 24 VDC input source, ensuring stable operation of CPUs, communication processors, and I/O modules.

This module supports parallel redundancy, allowing two units to operate simultaneously in load-sharing mode. In the event of a failure, the secondary module maintains uninterrupted power delivery, making it suitable for high-availability control systems where downtime is not acceptable.

Its electrical protection features, diagnostic signaling, and compliance with industrial standards make it a reliable component in critical process environments.

FAQ

Q: Can the 140CPS22424 operate in a non-redundant configuration? A: Yes, it can function as a standalone power supply, though redundancy is recommended for critical systems.

Q: What happens if one module fails in a redundant setup? A: The second module immediately assumes full load without interrupting PLC operation.

Q: Is this module compatible with Modicon X80 systems? A: No, it is specific to the Modicon Quantum platform. X80 systems require different power supply modules such as BMXCPS4022.
