Function and Working Principle
The S9185FA Battery Pack supplies backup power to compatible Yokogawa control equipment whenever the primary power source is interrupted. During normal operation, the battery remains on standby while the system operates from the main power supply.
If an unexpected power failure occurs, the battery automatically provides power to critical circuits, allowing important data such as controller memory, configuration parameters, and system time information to be retained. Once normal power is restored, the system resumes standard operation with all essential data preserved.
