Allen-Bradley 1769-L16ER-BB1B Programmable Logic Controller

The Allen-Bradley 1769-L16ER-BB1B CompactLogix 5370-L1 processor is a compact PLC designed for small automation tasks, delivering 16 digital inputs and 16 digital outputs on a 24 V DC I/O base. It provides 384 KB of user memory for ladder logic and data, enabling compact programs with real-time responsiveness in a compact control solution. As part of the CompactLogix 5370-L1 family, this controller is intended for integration into small machines and packaging or assembly cells that require reliable digital I/O and straightforward configuration. With its 24 V DC power requirement and 16DI/16DO I/O configuration, it supports direct interfacing to common factory sensors and actuators, making it a practical choice for simple sequencing, timing, and control tasks in compact automation projects. Allen-Bradley, a Rockwell Automation brand, designed the 1769-L16ER-BB1B to fit within existing 1769-series I/O ecosystems, offering a familiar software workflow for programming and diagnostics.
