Allen-Bradley 1756-L72 GuardLogix Processor Module

The Allen-Bradley 1756-L72 GuardLogix Processor Module is a GuardLogix-enabled CPU designed to run standard ControlLogix logic and safety-rated programs within a single controller. In GuardLogix 5572S configurations, it provides 4 MB of standard user memory and 2 MB of safety memory to store both control and safety data and logic. It integrates with GuardLogix safety I/O and safety modules to deliver hardware-enforced safety alongside conventional PLC operations, accessible through Rockwell Automation’s Studio 5000 environment. This processor is typically chosen for medium-to-large automation applications requiring tightly integrated safety and control, such as manufacturing lines and packaging systems, with standard Ethernet/IP networking within a GuardLogix system.
