The Allen-Bradley 1760-MM1 is a non-volatile memory module from the Rockwell Automation 1760 Pico Controllers series, compatible with both Series A and Series B Pico controllers. When used with Series B controllers, it operates as a read-only module. The 1760-MM1 memory module retains data without power loss and is designed to store backup copies of controller programs, transfer them to compatible controllers, and save controller parameters, system settings, and text display configurations for reliable program management in industrial automation systems.
