Allen-Bradley 1769-L19ER-BB2B CompactLogix 5370 L1 Controller Module
The Allen-Bradley 1769-L19ER-BB2B (Catalog Number: 1769-L19ER-BB2B) is a high-performance CompactLogix 5370 L1 controller designed for small to mid-size industrial automation applications. This module stands out by integrating a Logix CPU with embedded I/O in a slim, space-saving form factor. Specifically, the 1769-L19ER-BB2B features 1 MB of user memory and high-speed execution capabilities, making it ideal for localized machine control that requires the advanced features of a Rockwell PAC environment.
This controller supports up to 8 EtherNet/IP nodes and comes equipped with dual Ethernet ports to support Device Level Ring (DLR) topologies, ensuring network resiliency. The embedded I/O suite consists of 16 digital 24V DC inputs and 16 digital 24V DC outputs. For further flexibility, it supports the addition of up to 8 local 1734 POINT I/O modules via its integrated backplane connector. The 1769-L19ER-BB2B utilizes the Studio 5000 Logix Designer application, providing a unified engineering environment that enhances productivity and reduces commissioning time.
