The Schneider Electric 990XCP98000 is a dedicated lithium backup battery designed specifically for the Modicon Quantum automation platform. This high-reliability power source provides a stable 3 V DC supply to the CPU, ensuring that volatile RAM contents, ladder logic programs, and real-time clock data remain intact during power outages. By preserving these critical memory segments, the battery prevents data loss and minimizes the need for time-consuming system reloads or configuration recovery after a power interruption.

Features

  • Designed for seamless integration with Modicon Quantum CPU modules.
  • Utilizes Lithium-Thionyl Chloride (Li-SOCl2) chemistry for high energy density and stability.
  • Features a low self-discharge rate, supporting a service life of up to 10 years under standard operating conditions.
  • Equipped with a factory-standard wire lead connector for quick and secure installation.
  • Monitored by the CPU, with integrated support for BAT Alarm indicators to signal low voltage.
  • Supports hot-swappable replacement procedures while the processor remains powered.

Applications

This battery is essential for industrial environments where the preservation of real-time data and program continuity is mission-critical. Typical applications include, but are not limited to, petrochemical processing, water and wastewater management, thermal power generation, and large-scale automated manufacturing infrastructure.
