1756-BA1 ,It is designed to provide backup power to retain program data and maintain the real-time clock in the event of a power failure or interruption. The 1756-BA1 module is installed in the ControlLogix chassis and is typically used in conjunction with other modules to form a complete control system.

The 1756-BA1 module has a replaceable lithium battery that provides backup power for the ControlLogix system. It is important to periodically check the battery's status and replace it when its voltage drops below the acceptable threshold. This ensures reliable backup power and prevents data loss in case of a power outage.
