1756-L73 ControlLogix

The Allen-Bradley 1756-L73 is a ControlLogix 5570 series programmable automation controller (PAC) from Rockwell Automation. Featuring 8 MB of user memory, a built-in USB programming port, and support for up to 100 motion axes, this mid-range controller is engineered for medium-to-large industrial automation applications. Part of the mature 5570 platform, it provides a common control engine and development environment for discrete, process, motion, and drive applications. Program retention is maintained via an Energy Storage Module (ESM) that must be ordered separately.
