Allen Bradley 1762-MM1 MicroLogix 1200 Non-Volatile Memory Module

Product Overview

The Allen Bradley 1762-MM1 serves as a specialized non-volatile storage solution for the MicroLogix 1200 controller series. This plug-in module provides 8K words of memory to secure user programs and configuration data against power loss or hardware failure. It functions as a portable repository, allowing for rapid program duplication and deployment across multiple controllers. We supply this unit as 100% Brand New and Original, ensuring your critical logic backups reside on factory-fresh, high-integrity silicon.

Technical Specifications

The 1762-MM1 utilizes compact, reliable storage architecture for industrial environments:

Engineering Advantages

The 1762-MM1 solves several operational risks and maintenance bottlenecks in the automation lifecycle:

• Elimination of Battery Dependency: By migrating the user program from volatile RAM to the 1762-MM1 non-volatile flash, the system eliminates the risk of program loss during extended power outages or battery depletion.

• Rapid Machine Replication: OEM builders use the 1762-MM1 for "Master Program" transport. An engineer saves the tested logic to one module and simply plugs it into subsequent MicroLogix 1200 units on the production line, ensuring 100% code consistency across the fleet.

• Streamlined Field Replacement: In the event of a controller failure, onsite personnel simply move the 1762-MM1 from the old unit to the new one. The controller automatically detects the module and loads the application, restoring the machine to service without a laptop or software expert.

• Secure Data Archiving: The module supports "Store to Module" and "Load from Module" operations protected by controller passwords, ensuring that proprietary machine logic remains secure during transport or storage.

FAQs

• Does the 1762-MM1 store the data log and recipe files as well?

  The 1762-MM1 primarily stores the ladder logic program and configuration settings. While it secures the base application, you must configure specific data file protection in RSLogix 500 to ensure retentive data values transfer correctly during a module load.

• Can I use the 1762-MM1 with MicroLogix 1100 or 1500 controllers?

  No. The 1762-MM1 specifically fits the 1762 expansion slot architecture of the MicroLogix 1200. MicroLogix 1100 controllers utilize embedded flash, and MicroLogix 1500 units require 1764-series memory modules.

• How do I confirm the controller is actually using the memory module?

  You can configure the controller via software to "Load from Memory Module on Power-up." Additionally, the controller’s RUN LED flashes during the initial data transfer from the 1762-MM1, confirming a successful boot from the non-volatile source.

• What precautions should I take during installation?

  Always remove power from the MicroLogix 1200 before inserting the 1762-MM1. Static discharge can damage the module, so use a grounding strap or touch a grounded metal surface before handling the unit to ensure long-term reliability.
