ALLEN BRADLEY 1769-L38ERMS CompactLogix

The Allen-Bradley 1769-L38ERMS is a high-performance Compact GuardLogix 5370 L3 controller designed for applications that demand both standard and safety control, with integrated motion capabilities. It features 5 MB of standard user memory, 1.5 MB of dedicated safety memory, and includes a 1 GB non-volatile SD card (expandable up to 2 GB), allowing for efficient storage and fast recovery. The controller supports up to 32 tasks with a maximum of 1000 programs per task, and is programmable using Relay Ladder, Structured Text, Function Block, or Sequential Function Chart (SFC) through Studio 5000 or RSLogix 5000 software.

For communication, the 1769-L38ERMS offers dual 10/100 Mbps Ethernet ports with Device Level Ring (DLR) support, one USB 2.0 Type-B port for programming and maintenance, and full support for EtherNet/IP and TCP/IP protocols. It accommodates multiple network topologies, including star, linear, and ring configurations, and handles up to 80 EtherNet/IP nodes. In terms of I/O and motion control, this controller can manage up to 31 local Compact I/O modules across 3 I/O banks and supports up to 16 motion axes using CIP Motion and Kinematics for precise motion applications.

Engineered with safety in mind, the 1769-L38ERMS meets SIL 3 (IEC 61508) and Performance Level e (EN ISO 13849-1) standards. Its safety architecture includes features like dedicated safety memory, a safety task signature, safety I/O, and safety locking capabilities to ensure reliable operation in mission-critical environments. Physically, the unit measures 234 mm wide by 239 mm high and 155 mm deep, and is DIN rail mountable. An integrated display provides real-time status and diagnostic feedback, making it ideal for streamlined maintenance and monitoring in modern industrial control systems.
