Product Overview

The Schneider Electric 140CPS21400 functions as a high-efficiency power source for the Modicon Quantum automation platform. This module converts a wide-range 24 VDC input into a stabilized 5.1 VDC output, fueling Quantum CPUs, I/O modules, and communication interfaces within the rack. It features a summable architecture, allowing engineers to parallel multiple units to increase total current capacity or establish redundancy for mission-critical processes. We supply this product as 100% Brand New and Original to ensure maximum uptime in your industrial control systems.

Engineering Advantages

• Scalable Power Capacity: The summable design eliminates power bottlenecks. By installing multiple 140CPS21400 modules in a single rack, you achieve higher current totals without switching to complex external power configurations.

• Enhanced Fault Tolerance: The integrated "PWR OK" LED and NC fault contact provide immediate diagnostic feedback. The module triggers an alarm during power failures, allowing the control system to initiate safe shutdown procedures or switch to redundant backups instantly.

• Superior Noise Immunity: Designed specifically for the Modicon Quantum backplane, this module filters electrical noise and stabilizes voltage fluctuations inherent in heavy industrial environments like petrochemical plants and power generation facilities.

• Rapid Installation: The standard Modicon Quantum format ensures the module slides into the rack effortlessly. The 100 ms power interruption tolerance protects your CPU from data loss during brief voltage dips.

FAQs

• Does this module support redundancy?

  Yes. Because the 140CPS21400 is a summable power supply, you can use it alongside other summable modules to provide redundant power paths, ensuring the PLC remains operational even if one supply fails.

• What type of fuse should I use for the input protection?

  Schneider Electric recommends a 5 A slow-blow fuse to accommodate the initial inrush current (up to 25 A) while protecting the internal circuitry from sustained overcurrent conditions.

• Can the 140CPS21400 power the entire Quantum rack?

  It provides 8 A at 5.1 VDC. You must calculate the total current draw of your specific CPU and I/O modules. If your total demand exceeds 8 A, you simply add another summable module to the configuration.
