Allen-Bradley 1769-L33ER Series A CompactLogix Ethernet Processor

Product Overview

The 1769-L33ER (Series A) is a high-performance programmable automation controller (PAC) within the Allen-Bradley CompactLogix 5370 L3 family. Engineered for mid-range to complex automation tasks, it features 2 MB of user memory and integrated motion control over EtherNet/IP for up to 8 axes. The 1769-L33ER utilizes a battery-less design with an internal energy storage module, ensuring data retention during power loss without the maintenance overhead of traditional lithium batteries. Dual EtherNet/IP ports enable flexible network topologies, including Device Level Ring (DLR), making this processor a cornerstone for resilient, modern industrial architectures.
