Allen-Bradley 1756-L72 GuardLogix Processor Module

The Allen-Bradley 1756-L72 GuardLogix Processor Module is a safety-rated ControlLogix CPU in the GuardLogix family, featuring 4 MB of user memory and 2 MB of dedicated safety memory for safety programs and data. As a GuardLogix 5572S processor, it requires a Safety Partner to enable full functional-safety capability and works with GuardLogix I/O to deliver both standard control logic and safety-rated responses in a single system. In typical GuardLogix deployments, it can support large I/O configurations (up to thousands of digital and analog points in the same system) while storing the control application in user memory and the safety data in its separate safety memory, enabling robust, certified safety applications. The module is intended for safety-critical machinery across industries such as packaging, material handling, and automotive manufacturing, where proven reliability and integrated safety are essential. For connectivity, you pair this processor with a network/module option (for example Ethernet/IP via a compatible 1756-ENx module) to enable remote I/O, monitoring, and integration with Studio 5000 Logix Designer for programming and diagnostics. This processor serves as the central safety controller within GuardLogix configurations, coordinating safety logic with standard control tasks to meet stringent safety requirements while remaining part of the broader ControlLogix ecosystem.
