1769-L33ERMS Allen Bradley Compact GuardLogix CPU, L33ERMS, 2M/1M

The 1769-L33ERMS is a 5570 Compact GuardLogix controller that is manufactured by Allen-Bradley. This controller is capable of executing standard and safety functions as it features 2MB standard user memory and 1 MB safety memory. Additionally, this controller supports handling of up to 32 continuous and periodic tasks with each task having 100 programs each.

The 1769-L33ERMS is provided with dual Ethernet communication interface for connecting to an Ethernet I/P network. These dual ports carry the same network traffic and acts as embedded switch and uses a common I/P address. These ports support 10/100 Mbps transmission rate and capable of communicating up to 256 controller connections, 120 TCP connection, 256 CIP connection and maximum of 32 sockets. These ports may be used to exchange data with visualization systems such as Supervisory Control and Data Acquisition (SCADA) and Human Machine Interface (HMI) devices.

The 1769-L33ERMS supports installation of up to 16 local I/O modules and expansion using up to 3 I/O banks. Aside from the integrated safety feature, this controller supports motion over Ethernet I/P wherein up to 8 motion axes may be controlled. Supported programming languages are Relay Ladder Logic (RLL), Structured Text (ST), Function Block Diagram (FBD) and Sequential Function Chart (SFC).
