Allen-Bradley 1769-L24ER-QBFC1B Programmable Logic Controller

The Allen-Bradley 1769-L24ER-QBFC1B CompactLogix PLC controller combines integrated digital input/output and analog I/O with built‑in logic execution for mid-level industrial automation. Installed in control panels, machine automation racks, or distributed I/O systems, it enables synchronized discrete and analog signal handling with a program memory footprint of approximately 750 KB. The controller provides onboard digital I/O and analog I/O channels (model-dependent), communicates via EtherNet/IP with embedded industrial protocols, and is compatible with Studio 5000 Logix Designer for programming and configuration. Power is supplied from the CompactLogix chassis power rail, and mounting supports DIN rail or panel installation within a CompactLogix rack. It functions as a PLC control unit for discrete and analog process automation, handling logic, analog processing, and I/O management under industrial-rated operating conditions. For upgrades or replacements, common equivalents include Allen-Bradley 1769-L24ER, 1769-L35E, and 5069-L320ERM models.
