Overview
The Allen-Bradley 1756-M13/A is a memory expansion module designed for use with the ControlLogix 5555 Programmable Automation Controller (PAC) from Rockwell Automation. Its primary function is to increase the memory capacity of the controller, allowing it to store and process more data and programs. By providing an additional 1.5 megabytes of memory, this module allows for the development and execution of more complex programs, accommodating larger data sets and more intricate control processes.
Key Features
- Capacity: Increases the memory capacity of the ControlLogix 5555 PAC by 1.5 Megabytes.
- Non-Volatile Memory: Retains data even when the PAC is powered off.
- Hot-Swappable Design: Allows the module to be replaced without powering down the PAC.
- Safety Certifications: CE, C-UL, and UL listed: Meets safety and regulatory standards.
Technical Specifications
- Memory Expansion: 1.5 MB user memory
- Module Type: Non-volatile memory expansion
- Installation: Slot-based, integrated into ControlLogix chassis
- Operating Characteristics: Hot-swappable, no system power-down required
- Certifications: UL, C-UL, CE
Typical Applications
Expanding the memory of ControlLogix 5555 PACs for larger and more complex programs. Common use cases include:
- Large-scale manufacturing automation with complex sequencing logic
- Data-intensive applications requiring extensive data tables and arrays
- Multi-line or multi-plant consolidation on single PAC platforms
- Advanced motion control and synchronized process management
Compatibility & Replacements
Compatible with various ControlLogix controller models, including 1756-L55, 1756-L55M12, 1756-L55M13, 1756-L55M14, and others, the 1756-M13 ensures seamless integration into existing systems. It is built to fit directly into the memory slot of supported controllers, offering a reliable and efficient solution for expanding controller functionality. The 1756-M13/A is the Series A revision and is the direct replacement for earlier module revisions.
