Product Overview

The 1769-L24ER-QBFC1B (Catalog Number: 1769-L24ER-QBFC1B) is a highly integrated, all-in-one automation controller within the Allen-Bradley CompactLogix 5370 L2 family. This "packaged" controller is specifically engineered for small to medium-scale industrial applications that require a sophisticated blend of digital, analog, and high-speed motion control in a space-saving chassis.

By consolidating a 750 KB processor with an extensive embedded I/O bank—including 16 DC inputs, 16 DC outputs, 4 universal analog inputs, 2 analog outputs, and 4 high-speed counters—the 1769-L24ER-QBFC1B (Part Number: 1769-L24ER-QBFC1B) significantly reduces total hardware footprint and assembly time. The unit features dual EtherNet/IP ports to support Device Level Ring (DLR) topologies for enhanced network resiliency and utilizes a maintenance-free internal energy storage system, eliminating the need for replacement batteries.
