It includes two EtherNet/IP ports with Device Level Ring (DLR) capability for network redundancy, plus a 24 V DC embedded power supply. The unit provides 750 KB (0.75 MB) of user memory for logic and data, and built-in I/O of 16 digital inputs and 16 digital outputs, all at 24 V DC. It supports up to four additional 1769 I/O expansion modules to scale I/O as your application grows, and can host up to eight EtherNet/IP nodes and 120 TCP connections on the network. For onboard storage and firmware management, it ships with a 1 GB SD card and supports SD cards up to 2 GB, and it includes a USB port for programming and file transfer. As part of the CompactLogix 5370 L2 family, the 1769-L24ER-QB1B is suited for distributed control in machines, packaging lines, conveyors, and other compact automation environments that require reliable Ethernet connectivity and scalable I/O within a single small-form controller.
