Allen‑Bradley 1756‑BA2 Memory Module | for ControlLogix L6x, 2MB Flash

Allen‑Bradley 1756‑BA2 controller memory specifications. 2MB non-volatile flash memory module for ControlLogix L6x processors.

Product Overview

The Allen‑Bradley 1756‑BA2 is a non-volatile flash memory module for ControlLogix 5560 series controllers (specifically L6x models). It is used to store and back up the controller's project data, including ladder logic, tags, and configuration, providing a reliable, non-volatile storage solution separate from the controller's internal memory.

Technical Specifications

Key Features

• Project Backup:​ Provides secure storage for the controller's project file

• Non‑Volatile Storage:​ Retains program and data even when controller power is removed

• Firmware Updates:​ Can store controller firmware for updates

• Easy Transfer:​ Facilitates transfer of projects between controllers

• Direct Integration:​ Plugs directly into the processor module; no chassis slot required

• Reliable Design:​ Industrial-grade flash memory for reliable operation

Applications

• Backup storage for ControlLogix L6x controller projects

• Transferring control programs between identical controllers

• Storing firmware updates for offline controller updates

• Providing a recovery option in case of controller memory corruption

• Standard practice in ControlLogix systems for program security and maintenance

Important Notes

1. Compatible only with specific ControlLogix 5560 L6x series processors

2. Memory capacity is fixed at 2MB; verify project size does not exceed capacity

3. Not a runtime memory expansion; does not increase controller's scan time capacity

4. To function, must be properly installed and the controller must be configured to use it

5. Always follow proper ESD procedures when handling the memory module
