Allen-Bradley 1769-PB2 CompactLogix DC 2A/0.8A Power Supply 1769PB2

Description:

The Allen-Bradley 1769-PB2 CompactLogix DC Power Supply is used in CompactLogix and MicroLogix 1500 control systems to provide regulated backplane power to 1769 Compact I/O modules. Commonly installed in industrial control panels for packaging equipment, conveyor systems, machine automation cells, and process control skids, it supplies stable DC power for controller and I/O module operation. Maintenance teams and system integrators use this power supply for system builds, panel retrofits, capacity expansion, and replacement of failed Compact I/O power units in distributed automation systems. 

Applications:

The 1769-PB2 power supply is applied in manufacturing lines, material handling systems, water and wastewater control panels, automotive assembly equipment, and OEM machinery where CompactLogix or MicroLogix 1500 platforms require reliable 24V DC input power to maintain consistent I/O backplane performance.
