Allen-Bradley 1769-L19ER-BB1B Programmable Logic Controller

The Allen-Bradley 1769-L19ER-BB1B CompactLogix PLC processor provides approximately 1 MB of program and data memory for mid-range automation tasks, making it well suited for reliable real-time control in industrial environments. As part of the CompactLogix 5370 family, it executes ladder logic and sequencing, handles I/O scanning, and supports real-time control with built-in EtherNet/IP and industrial protocol connectivity. Programming is done with Studio 5000 Logix Designer. It interfaces with I/O modules via an integrated backplane and is powered from the CompactLogix system power rail. Mounting options include DIN rail or panel mounting within a CompactLogix rack. Common applications include manufacturing production lines, material handling, HVAC control panels, packaging machinery, water and wastewater facilities, and automated assembly equipment. Operating conditions are industrial-rated. Common replacements include 1769-L23ER, 1769-L30ER, and 5069-L320ERM.
