Overview
The Allen-Bradley 1769-L30ERM is a CompactLogix 5370 L3 motion controller designed for compact industrial automation and motion control applications. This unit comes new in box and combines integrated motion control capability with dual Ethernet connectivity, making it ideal for applications requiring synchronized multi-axis control over EtherNet/IP networks.
Key Features
- Integrated 4-Axis CIP Motion Control — Supports up to four motion axes natively, eliminating the need for separate motion modules
- 1MB User Memory with SD Card Expansion — Ships with 1GB SD card; expandable up to 2GB for program and data storage
- Dual Ethernet/IP Ports with DLR — Supports Device Level Ring (DLR), linear, and star topology; accommodates up to 16 EtherNet/IP nodes
- Eight I/O Expansion Slots — Supports up to 8 compact I/O modules with 3 expansion banks
- IEC 61131-3 Programming — Compatible with Relay Ladder, Structured Text, Function Block Diagram, and Sequential Function Chart (SFC)
- No Embedded I/O — Flexible modular architecture; I/O configured via compact plug-in modules
