Product Description

The Allen-Bradley 1769-L24ER-QB1B (Catalog Number: 1769-L24ER-QB1B) is a highly integrated CompactLogix 5370 L2 controller designed for small to mid-sized automation applications. Unlike the L3 series, the 1769-L24ER-QB1B features an embedded I/O configuration, providing a ready-to-use control solution that minimizes cabinet space. This specific unit is a Used Series A revision, offering a cost-effective entry point for system maintenance or machine retrofits while maintaining the robust processing power of the Logix engine.

This controller is equipped with 0.75 MB of user memory and features dual EtherNet/IP ports with an integrated switch, supporting Device Level Ring (DLR) topologies for high network availability. The embedded I/O suite includes 16 digital 24V DC inputs and 16 digital 24V DC outputs (source), making it ideal for discrete manufacturing tasks. Additionally, it supports up to 4 local 1769 Compact I/O expansion modules and up to 8 EtherNet/IP nodes, providing significant scalability for distributed control and integrated motion.
