Allen-Bradley 1769-L18ERM-BB1B CompactLogix Controller

The Allen-Bradley 1769-L18ERM-BB1B CompactLogix Controller is a CompactLogix 5370 L1 processor with integrated motion capability, delivering 512 KB of user memory and a 1 GB SD card included for project storage and data logging, making it a compact, motion-enabled PLC option. Powered by 24 VDC, it provides 16 discrete inputs (sink) and 16 discrete outputs (source) on the on-board I/O, and supports up to eight expansion modules via the POINT Bus backplane, enabling scalable local and remote I/O configurations in tight machine footprints. Networking features include two Ethernet ports (DLR) for EtherNet/IP communication and support for up to eight Ethernet/IP nodes, facilitating reliable device-to-device communication, remote monitoring, and easy integration with Rockwell Automation and third-party devices in small to mid-size automation systems. Programming options include ladder logic, structured text, function block, and sequential function charts, and the controller supports integrated motion over EtherNet/IP for 1–2 axes, allowing synchronized motion control without a separate motion controller.
