About the Allen-Bradley 1769-L33ERMS

The Allen-Bradley 1769-L33ERMS is a Compact GuardLogix 5370 safety controller for 1769 Compact I/O. Rockwell's technical data gives it 2 MB of standard memory and 1 MB of safety memory, 32 EtherNet/IP nodes and up to 8 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-L320ERMS3 as its engineering replacement.

What is the 1769-L33ERMS used for?

The 1769-L33ERMS 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.
