Applications
The 1769-BA is ideal for manufacturing plants, process control systems, and any facility relying on CompactLogix controllers for critical operations. It ensures that your programs and data remain safe during unexpected shutdowns, minimizing downtime and preventing costly reprogramming.
Installation & Replacement
To replace an existing 1769-BA, the controller must be actively powered to retain memory. Remove the old battery and insert the new one, ensuring correct orientation. The battery is used only when the controller is powered down; if non-volatile memory (SD or CompactFlash) is installed, the battery can be removed even when powered off. Always dispose of old batteries according to local regulations.
Maintenance & Storage
Store the 1769-BA in a cool, dry, well-ventilated area, away from direct sunlight, water, and heat sources. Avoid short-circuiting, disassembling, or incinerating the battery. When replacing multiple batteries, replace all at once. Monitor the BAT indicator; when it activates, replace the battery promptly to avoid data loss.
Compatibility & Integration
The 1769-BA is designed for use with the Allen-Bradley CompactLogix series, specifically the 1769-L2x and 1769-L3x controllers. It maintains volatile memory, ensuring seamless operation with your existing control system.
Selection Guide
When purchasing a replacement battery, verify that your controller model is listed as compatible. For bulk orders or OEM applications, ensure the battery meets your regulatory requirements. PLC Source PRO offers genuine Allen-Bradley 1769-BA modules with fast shipping and competitive pricing.
