PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1769-L37ERM is a CompactLogix controller designed for automation control and multi-axis motion. It provides 4 MB of user memory for program execution and data handling. The unit executes up to 32 concurrent tasks. Each individual task supports up to 100 separate programs. Integrated motion capabilities manage control for up to 16 axes across automation systems.
Network communication uses two EtherNet/IP ports with RJ45 connectors alongside one USB Type B port. The controller supports up to 64 EtherNet/IP nodes. It operates across linear network architectures and Device Level Ring topologies. Non-volatile storage includes a 1 GB Secure Digital card for data retention. Backplane current consumption draws 1.2 A at 5V DC and 0 mA at 24V DC.
