Allen-Bradley 1769-L18ER-BB1B Compact IO Module

The Allen-Bradley 1769-L18ER-BB1B is a CompactLogix 5370 L1 processor with dual Ethernet ports and Device Level Ring (DLR) functionality, engineered for compact, reliable Ethernet/IP-based control in small-to-mid-size machines. Operating from 24 VDC, it houses 512 KB of user memory for programs and data and supports up to eight 1734 POINT I/O expansion modules to extend I/O points through the 1769 I/O backplane. This CPU integrates into a CompactLogix 5370 L1 system to deliver a space-saving control solution with redundancy-friendly networking, enabling straightforward connectivity to EtherNet/IP networks while maintaining centralized programming through legacy RSLogix 5000 software compatibility. Ideal for applications that require distributed I/O and network resilience in a compact package, the 1769-L18ER-BB1B combines Ethernet connectivity, scalable I/O expansion, and compact form factor to simplify integration in automated workflows.
