1756-L6x Series B controllers, the battery assembly installs directly into the controller chassis using a prewired connector. With a nominal output of 3 VDC and a capacity of 1200 mAh, the unit provides long-term backup capability and typically delivers a service life of at least three years under recommended environmental conditions.
The 1756-BA2 is widely used in manufacturing plants, power generation facilities, water treatment systems, oil and gas installations, and other industrial automation environments where uninterrupted retention of PLC memory is critical for operational continuity.
- Factory Automation: Protects PLC logic routines in control panels from sudden grid failures
- Continuous Process: Prevents costly reprogramming and product loss in chemical, refining, and food plants
- CNC Machining: Safeguards calibrated axis positions and cutting routines during power fluctuations
- Data Logging: Preserves runtime metrics and alarm history until power is safely restored
