Allen-Bradley 1756-L55M13 ControlLogix 5555 Processor Module
The Allen-Bradley 1756-L55M13 is a powerful ControlLogix 5555 controller featuring 1.5MB of user memory. This versatile processor supports diverse industrial protocols, provides high-speed logic execution, and offers optional redundancy for demanding PLC applications.
Product Description
The Allen-Bradley 1756-L55M13 represents a high-capacity processing solution within the ControlLogix 5555 controller family. Engineered for complex automation sequences, this module provides 1.5 megabytes of dedicated user memory alongside 208 kilobytes of specialized I/O memory. Because this processor manages intensive data and logic routines, it serves as the primary intelligence for large-scale industrial systems. Users often deploy this unit in multi-disciplinary applications where high-speed motion control and discrete logic must reside on the same platform.
This controller excels in connectivity, bridging disparate networks such as EtherNet/IP, ControlNet, and DeviceNet through the 1756 backplane. While the 1756-L55M13 operates as an open-style module, its rugged internal design handles significant mechanical stress, including operational shocks up to 30g. To ensure system reliability during power cycles, the module utilizes a 1756-BA1 lithium battery for volatile memory retention. Furthermore, this processor supports full controller redundancy when paired via ControlNet, which effectively eliminates single points of failure in mission-critical manufacturing environments. By integrating this module into a standard ControlLogix chassis, operators gain a flexible, scalable, and powerful tool for modern process control.
