Allen-Bradley 1769-L30ER CompactLogix Controller

The Allen-Bradley 1769-L30ER CompactLogix 5370 L3 Ethernet/IP Controller is a compact, dual‑Ethernet PLC designed for small to mid‑size automation tasks, delivering a dedicated 1 MB of user memory and support for up to 8 local 1769 I/O expansion modules (up to 256 local I/O points) with the ability to address up to 16 EtherNet/IP nodes in a single project. It features Dual Ethernet with Device Level Ring (DLR) capability for network redundancy, an integrated SD memory card slot (1 GB shipped, with 1–2 GB options available), and firmware support for CompactLogix 5370 L3 controllers (example firmware v38.011). Integrated motion support is available for up to 4 CIP axes, enabling basic motion and coordinated control within a CompactLogix environment. This controller is designed to work with Rockwell Automation software such as RSLogix 5000 and RSLinx Classic for configuration and commissioning, and its physical footprint measures 55 mm wide by 118 mm high by 105 mm deep. The 1769-L30ER is built to UL 508 and CE standards, aligning with common industrial control certifications, making it suitable for small to medium industrial applications that require reliable Ethernet/IP connectivity, modest expansion, and straightforward motion capabilities without the need for a larger chassis.
