About the Allen-Bradley 1769-L37ERMS

The Allen-Bradley 1769-L37ERMS is a Compact GuardLogix 5370 safety controller for 1769 Compact I/O. Rockwell's technical data gives it 4 MB of standard memory and 1.5 MB of safety memory, 64 EtherNet/IP nodes and up to 16 axes of integrated motion, and Rockwell's description adds two Ethernet ports with DLR capability and a 1 GB SD card shipped with the controller. Rockwell names the 5069-L340ERMS3 as its engineering replacement.

What is the 1769-L37ERMS used for?

The 1769-L37ERMS runs the control program on a machine or line, working with 1769 Compact I/O and devices on EtherNet/IP. It runs standard and safety control in one controller.
