Yokogawa S9450FE Backup Battery for CENTUM VP / CS 3000

Product Overview

The Yokogawa S9450FE serves as the high-capacity backup power solution for CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This 100% Brand New original Lithium-Ion module provides critical energy reserves to CPU modules and memory boards. It prevents the loss of volatile system data, process variables, and alarm logs during primary power interruptions or scheduled maintenance windows. Unlike standard consumer cells, the S9450FE utilizes industrial-grade Lithium-Ion chemistry to deliver the high energy density and stable 3V output required by mission-critical control architectures in the oil, gas, and petrochemical sectors.

Technical Specifications

Engineering Advantages

• High Energy Density for Extended Uptime: The Lithium-Ion chemistry of the S9450FE offers significantly higher energy density compared to traditional Ni-Cd alternatives. This ensures longer backup durations, allowing the DCS to maintain memory integrity during extended facility-wide power outages.

• Rapid Response Power Transition: The module integrates seamlessly into the Yokogawa backplane to provide instantaneous power switching. This eliminates voltage sags that cause CPU resets, ensuring that the control system recovers its last known state immediately upon power restoration.

• Industrial-Grade Vibration Resistance: Yokogawa builds the S9450FE to withstand the constant mechanical vibrations prevalent in industrial turbine halls and manufacturing floors. The ruggedized 2 kg housing ensures the internal cells maintain secure electrical contact under heavy operational stress.

• Thermal Stability in High-Density Racks: The battery chemistry and enclosure design manage heat dissipation effectively. This allows the module to operate reliably within the high-temperature environment of a fully populated DCS cabinet without degrading the service life of the cells.

• Maintenance-Optimized Form Factor: The 150mm x 115mm x 90mm dimensions facilitate easy installation into standard Yokogawa control racks. Technicians can replace the module during live system operation (following standard safety protocols) to ensure continuous protection for volatile data.

FAQs

• Q: Does the S9450FE require a full charge before installation?

• A: This Brand New module arrives with a factory-specified charge. Once you integrate it into the CENTUM system, the DCS charging circuitry takes over to maintain the battery at its optimal 3V nominal voltage.

• Q: Can the S9450FE replace older Ni-Cd battery modules?

• A: While the S9450FE is the standard for modern CENTUM VP and CS 3000 systems, you must verify your specific CPU baseplate's support for Lithium-Ion charging profiles. Consult your system manual to ensure the charging circuitry matches this 3V Li-ion specification.

• Q: How does the 2 kg weight benefit the installation?

• A: The substantial weight of the S9450FE reflects its high cell density and ruggedized internal shielding. This weight, combined with the secure mounting mechanism, prevents the module from shifting or losing connection in high-vibration industrial environments.

• Q: What happens if the S9450FE voltage drops below 3V?

• A: The CENTUM system continuously monitors battery health. If the voltage drops below the safe threshold, the system triggers a "Battery Low" alarm on the Operator Station, notifying maintenance personnel to replace the module before data integrity is compromised.
