The Allen Bradley 1769-L30ERM is one version a CompactLogix 5370 controller that can run up to 32 tasks at a time. This module is equipped with a user memory of 1 MB and an optional nonvolatile 1784-SD1 card with 1 GB of additional memory. The controller’s current draw at 5 Volts DC and at 24 Volts DC are 500 mA and 225 mA, respectively. The maximum power dissipation of the 1769-L30ERM is 4.5 W. This module is 2.17 inches wide and can be mounted on a panel or DIN rail.
The Allen-Bradley 1769-L30ERM can send and receive messages on multiple networks and control any distributed Input or output. This module supports a temporary connection from your computer via a USB connection. The Ethernet/IP network provides a full suite of control services, configuration features, and data collection systems. The 1769-L30ERM supports Quality of Service (QoS) technology that allows controllers to prioritize Ethernet/IP network traffic.

The 1769-L30ERM is an Allen-Bradley product that belongs to the Programmable Automation Controller (PAC) product family. This product in particular is a 1769 CompactLogix controller that features modular features and integrated with motion control capability over Ethernet network.

This controller features a user memory that amounts to 1MB and an integrated 1Gb non-volatile memory that ships with the controller provided by the 1784-SD1 memory card.
This controller is also installed with Dual Ethernet communication port, and a single USB port. The dual Ethernet port supports Linear, Ring, and Star topologies. It also functions as an integrated switch.
Up to Four axes of motion control can be controlled by this controller. The module does not come with an integrated Input and Output channels however, supports a larger number of local 1769 Compact I/O modules wherein up to Eight (8) modules m be stalled. It also supports a higher number of expansion I/O banks, specifically, up to Three (3) I/O banks .
For Version 21.XX and later, use Studio 5000 Logix Designer. Either instances, the controller’s user programming may be programmed with IEC 61131-3 programming languages such as Relay Ladder, Sequential Function Chart (SFC), Statement List (STL) and Function Block Diagram (FBD).
