Core Function for High-Availability Systems

The Schneider 140CPS52400 is a redundant power supply module for the Modicon Quantum series. This unit provides a stable and reliable 5.1VDC output to the system’s backplane and modules. It is specifically designed for redundant configurations to ensure uninterrupted control system operation. Consequently, it is a critical component for applications demanding maximum uptime and fault tolerance in process automation.

Redundant Output and Robust Electrical Design

This module delivers up to 8 amps of output current when configured in a redundant pair. It operates from a 125VDC nominal input, with a functional range from 100 to 150 VDC. The 140CPS52400 features a maximum power interruption tolerance of just 1 millisecond for seamless operation. Furthermore, it includes a 2-amp slow-blow fuse for overcurrent protection and can withstand a high inrush current of 28A.

Detailed Technical Specifications

Engineered as a standard-format Quantum module, it integrates cleanly into existing system racks. Its design meets CE marking standards for safety and electromagnetic compatibility. The following table details its complete electrical input, output, and protection parameters.

Application in Critical Control Environments

Install this module in a redundant pair to provide fault-tolerant power to your Quantum PLC or DCS rack. This configuration ensures that if one power supply fails, the other immediately carries the full load. The Schneider 140CPS52400 is essential for power generation, water treatment, and chemical processing plants. Therefore, it is a foundational component for building resilient and highly available industrial control architectures.
