Allen-Bradley 1769-L33ER Detailed Description
High-Performance CompactLogix 5370 L3 Controller for Machine-Level Control
The Allen-Bradley 1769-L33ER is a high-performance CompactLogix 5370 L3 controller built for mid-size automation and industrial control applications. As part of Rockwell Automation’s CompactLogix family, this programmable automation controller delivers 2 MB of user memory, 32 tasks with up to 100 programs per task, and integrated dual-port EtherNet/IP connectivity with an embedded switch — all in a compact, DIN rail or panel mountable package. Whether you are building a new machine-level control system, upgrading an aging PLC processor, or replacing a failed CompactLogix controller, the 1769-L33ER provides the processing power, I/O density, and network flexibility modern production environments demand.
Key Features & Benefits
- 2 MB user memory — generous capacity for complex logic, data logging, and multi-program applications; 32 tasks with 100 programs per task.
- Dual-port EtherNet/IP with embedded switch — daisy-chain (DLR) topologies without an external switch; both ports carry the same network traffic while the controller uses a single IP address; supports up to 32 EtherNet/IP nodes and 256 controller connections.
- USB programming port — temporary direct connection for configuration with Studio 5000 Logix Designer (RSLogix 5000) software.
- Up to 16 local I/O modules in 2 banks — connect the full range of 1769 CompactLogix digital, analog, and specialty I/O modules for dense machine control.
- DeviceNet support — add a 1769-SDN scanner module to integrate DeviceNet devices into the same control architecture.
- Removable 1784-SD1 SD card (1 Gb) — shipped with the controller for nonvolatile storage, fast replacements, and program backup.
- Flexible mounting — DIN rail or panel mount with a slim 55 mm body depth that conserves enclosure space.
- Wide 0 to 60 °C operating range — reliable operation in demanding industrial environments; 10 to 500 Hz vibration rating.
Compatible Hardware
The 1769-L33ER works with all 1769 CompactLogix I/O modules (digital input/output, analog input/output, specialty and communication modules such as the 1769-SDN DeviceNet scanner), 1769 power supplies, and PanelView Plus operator interfaces. It is programmed with Studio 5000 Logix Designer (formerly RSLogix 5000) and integrates seamlessly into FactoryTalk-enabled architectures. For safety-rated applications, consider the 1769-L33ERMS Compact GuardLogix variant.

Why Choose the Allen-Bradley 1769-L33ER
The 1769-L33ER strikes the balance between the entry-level L30ER and the motion-focused L33ERM: it adds the 2 MB memory, 32 EtherNet/IP nodes, and 256 controller connections that growing machines need, without the cost of integrated CIP Motion. Plants standardizing on Rockwell Automation’s Logix platform benefit from common programming tools, spare-parts interchangeability, and straightforward migration paths to larger controllers. Every Allen-Bradley 1769-L33ER we ship is tested, backed by warranty, and available both new in original packaging and as a cost-saving refurbished unit.
