Schneider 140XCP51000

Product Overview

The Schneider Electric 140XCP51000 is a high-quality battery backup module specifically designed for use with the Modicon Quantum series of programmable logic controllers (PLCs). It plays a vital role in preserving system memory and maintaining control system integrity in the event of power loss or planned shutdowns.

This module is used to supply backup power to the Real-Time Clock (RTC) and volatile memory components of the CPU unit in a Quantum system. It ensures that time-stamped data, configuration parameters, and other critical variables are not lost when the main power supply is removed. The 140XCP51000 is typically mounted in close proximity to the CPU and connects through a standard interface for seamless integration.

By acting as a reliable energy storage device, it supports the robustness and resilience of the automation system, especially in industrial environments where continuous uptime, data preservation, and fault tolerance are critical.

Key Features

• Long-Lasting Lithium Battery
  The module contains a factory-installed lithium battery with a long service life, often exceeding 10 years under normal operating conditions. This ensures minimal maintenance and reduces the risk of unexpected battery failure.

• Compact and Lightweight Design
  Designed with space efficiency in mind, the 140XCP51000 fits easily into control enclosures or within dedicated PLC racks. Its form factor does not interfere with other modules and simplifies installation.

• Direct CPU Connection
  Provides a plug-and-play connection to the Quantum CPU, eliminating the need for external cabling or adapters. It integrates directly into the power architecture of the controller.

• Battery Health Monitoring
  The Quantum CPU continuously monitors the status of the backup battery. Any drop in voltage or expected service life can be detected early, prompting timely maintenance actions via diagnostic messages.

• Reliable Backup During Power Loss
  Prevents loss of volatile memory contents and ensures that system time and logged event sequences are preserved during power interruptions or system shutdowns.

• Temperature-Resistant Design
  Capable of operating in typical industrial temperature ranges, the battery pack performs consistently even in harsh environments.

• Maintenance-Friendly
  The unit can be easily replaced without dismantling the entire PLC system. Clear labeling and documentation simplify the replacement process for maintenance personnel.

Applications

The 140XCP51000 is used in a wide range of automation systems, particularly those requiring high reliability, data integrity, and long-term operation. Common application areas include:

• Process Automation
  In chemical processing, refining, and pharmaceutical manufacturing plants where process data and control logic must be preserved across shutdowns.

• Power Generation and Utilities
  Used in power plants, substations, and water treatment facilities, where the loss of time-based logs or memory could result in operational setbacks or regulatory issues.

• Automotive and Discrete Manufacturing
  Ensures that configuration settings, production batch records, and system clocks are maintained between power cycles in high-speed, automated production environments.

• Transportation Infrastructure
  Used in railway control systems, tunnel monitoring, and airport automation where control systems must remain synchronized and consistent despite environmental changes or brief power outages.

• SCADA and Remote Systems
  Vital for maintaining operational continuity in remote installations with limited access and fluctuating power sources.
