Specification

SEODescription

The Allen-Bradley 1761-L16BBB is a compact PLC module designed for small-scale automation, featuring 16 digital I/O points (10 inputs and 6 outputs) to handle basic control tasks. This 1761-L16BBB digital I/O module supports direct connectivity with up to three expansion modules, enabling flexible system configurations. It integrates an RS-232 communication port for programming and DF1 protocol compatibility, ideal for integration into legacy or simple networks. Operating at 24V DC with a temperature range of 0–55°C, the 1761-L16BBB PLC module is suited for industries like manufacturing, water treatment, and packaging. Key advantages include its compact design, ease of installation, and compatibility with Rockwell software, though its limited I/O capacity and lack of advanced communication interfaces (e.g., Ethernet) restrict scalability for larger applications.
