Product Description
The S9883FA is a high-capacity lithium thionyl chloride (Li-SOCl₂) backup battery designed for use with Yokogawa Electric Corporation control platforms, including STARDOM FCN/FCJ controllers and select legacy RTU processor modules.
This battery safeguards CMOS memory, runtime variables, and the real-time clock (RTC) during primary power interruptions. Engineered for industrial reliability, it provides a stable discharge voltage and extremely low self-discharge rate, making it ideal for remote or unmanned installations where long-term data retention is critical.

System Integration & Maintenance
The S9883FA plays a critical role in autonomous Field Control Nodes (FCN). Without a functional backup battery, loss of primary power may result in:
-
Loss of application program stored in SRAM
-
Reset of real-time clock
-
Loss of runtime or temporary historical data
For preventive maintenance, engineers typically replace the battery before the “Battery Low” LED indicator activates on the controller front panel. Scheduled replacement minimizes the risk of unexpected data loss.
Frequently Asked Questions
Is the S9883FA rechargeable?
No. It is a primary (non-rechargeable) lithium battery. Attempting to recharge it can cause leakage, overheating, or damage to the controller PCB.
Can it be replaced while the controller is powered?
Yes. It is recommended to replace the battery while the CPU remains powered to prevent any temporary loss of memory during the swap process.
