The Allen‑Bradley 1769‑L33ER is a CompactLogix™ 5370 L3 programmable automation controller designed for medium‑sized machines and control systems requiring higher performance, increased memory capacity, and scalable Ethernet connectivity. It is well suited for applications that need reliable control, distributed I/O, and seamless integration into EtherNet/IP networks.
This controller features 2 MB of user memory, providing ample capacity for complex logic, device communication, and data handling. Unlike packaged L1/L2 controllers, the 1769‑L33ER is a modular controller, allowing flexibility in system design when paired with appropriate power supplies and I/O modules.
The 1769‑L33ER includes dual EtherNet/IP ports, enabling high‑speed communication with HMIs, drives, distributed I/O, and other controllers while supporting linear and star network topologies. Its Ethernet capabilities make it ideal for modern, network‑centric automation architectures.
Supporting a wide range of 1769 Compact I/O modules, the controller allows systems to scale easily as application requirements grow. It is fully programmable using Studio 5000 Logix Designer, ensuring seamless integration with Rockwell Automation’s Logix platform.
Overall, the 1769‑L33ER delivers a strong balance of processing power, memory, and Ethernet connectivity, making it an excellent choice for machine builders and system integrators seeking a reliable controller for flexible, expandable industrial automation systems.

The Inline controller offers the option of communicating via PROFINET and Modbus/TCP. Programming is carried out using PC Worx Express or PC Worx (IEC 61131-3).
