Allen-Bradley 1769-L16ER-BB1B CompactLogix Controller is a compact, 24 V DC-powered PLC module that combines 16 discrete inputs (sink) and 16 discrete outputs (source) in a single unit. It provides two Ethernet ports (DLR) for device‑level networking and supports up to four Ethernet/IP nodes on the network. Designed for scalable automation, it attaches to a POINT Bus backplane and supports up to six expansion modules to extend I/O capacity. The controller includes 384 KB of user memory and ships with a 1 GB SD card for program storage and data logging, enabling local data retention and firmware storage.
