Schneider Electric 140CPS21400C | Conformal Coated 24V Supply

Schneider Electric 140CPS21400C Modicon Quantum DC Power Supply Module

The 140CPS21400C (Model: 140CPS21400C) is a high-reliability DC power supply module engineered for the Schneider Electric Modicon Quantum automation platform. Designed to convert a nominal 24 VDC source into a regulated 5.1 VDC output, this module provides the essential energy required by the PLC backplane and its associated I/O modules. The 140CPS21400C (Part Number: 140CPS21400C) is specifically characterized by its "summable" capability, allowing multiple units to be installed in parallel to increase the total current capacity of the system or provide redundancy.

This module is built for resilience in demanding industrial settings, featuring a robust 100 ms power interruption ride-through capability at nominal voltages. It includes a built-in "Power OK" relay contact for remote diagnostic monitoring and integrated protection against overvoltage and overload conditions. The "C" suffix in the 140CPS21400C (Quantum Power: 140CPS21400C) indicates a conformal coating, providing superior protection against moisture, dust, and chemical contaminants in harsh processing environments.
