Technical Specification and Product Overview – Schneider 140XCA71709
1. Product Identification
Model: 140XCA71709
Product Type: PLC Redundant Power Supply Module
Category: Modular PLC System Power Infrastructure
2. Product Introduction
The 140XCA71709 is a redundant power supply module designed to deliver reliable and continuous power to modular programmable logic controller (PLC) systems. Redundancy in power supply means that two power units operate in parallel so that if one fails, the other can continue supplying power without system interruption. This feature is critical in industrial automation systems where unexpected downtime can lead to safety hazards, production loss, or costly system resets.
This model is specifically configured to provide robust performance in demanding industrial environments. It manages power distribution to the backplane and connected modules while offering protections against overvoltage, overload, short circuits, and thermal stress. The 140XCA71709 ensures system stability by maintaining uninterrupted power delivery even during component failures, making it essential for mission‑critical automation applications.
The module is engineered for seamless integration into standard PLC backplane racks. Its design facilitates simple installation, reliable operation, and ease of maintenance—all of which contribute to higher uptime and improved longevity of the control system.
