S9883FA Yokogawa Industrial DCS Backup Power Cell

Product Overview

The Yokogawa S9883FA serves as the primary failsafe for CENTUM VP and CENTUM CS 3000 control platforms. This 3.6V lithium battery provides critical backup power to CPU modules and memory boards. It prevents volatile data loss during sudden power interruptions, maintaining the integrity of system configurations and operational parameters. By utilizing Lithium Thionyl Chloride (Li-SOCl₂) chemistry, this unit delivers high energy density and voltage stability required for high-stakes industrial automation.

Technical Specifications

Engineering Advantages

• Superior Thermal Stability: The Li-SOCl₂ chemistry allows the S9883FA to operate reliably in the extreme heat of dense DCS cabinets and the vibration-heavy environments of chemical plants.

• Low Self-Discharge Rate: This battery maintains its charge during long periods of system inactivity, ensuring that backup power remains available even after extended shutdowns.

• Data Integrity Protection: The S9883FA eliminates the risk of "cold start" data loss. It powers the Static RAM (SRAM) instantly when the main power rail drops, preserving your logic and runtime variables.

• Ruggedized Enclosure: The housing resists industrial contaminants and prevents leakage, protecting sensitive CPU electronics from chemical damage over years of service.

FAQs

Q1: How does the S9883FA handle high-temperature industrial environments?

A1: Yokogawa builds the S9883FA using Lithium Thionyl Chloride, which remains stable at much higher temperatures than standard alkaline or consumer lithium cells. This prevents voltage sag and internal pressure buildup within DCS control cabinets.

Q2: Does this battery require periodic maintenance?

A2: While the battery is maintenance-free, system engineers should monitor the "Battery Low" alarm on the CENTUM HIS (Human Interface Station). We recommend replacing the unit within the manufacturer’s specified service interval to ensure 100% uptime.

Q3: Is the S9883FA compatible with older Yokogawa hardware?

A3: Yes, the S9883FA supports both the modern CENTUM VP series and the legacy CENTUM CS 3000 systems. It functions as a direct, high-reliability replacement for standard 3.6V backup modules in these architectures.

Q4: What is the shelf life of a brand-new S9883FA?

A4: Thanks to its low self-discharge characteristics, a brand-new, sealed S9883FA typically maintains a shelf life of up to 10 years when stored in a cool, dry environment. We supply only 100% original, recently manufactured stock to maximize this lifespan.
