1747-M1 | Allen Bradley SLC 500 EEPROM Memory Module

Product Overview

The Allen Bradley 1747-M1 functions as a high-integrity non-volatile memory storage solution for the SLC 500 controller platform. This EEPROM module provides a secure repository for user programs and data tables, ensuring the processor retains critical logic during power loss or battery failure. We supply this component as 100% Brand New and Original, serving as a vital hardware backup for legacy SLC 5/01 and 5/02 systems to prevent costly downtime and loss of automation code.

Technical Specifications

The 1747-M1 provides specialized storage parameters for SLC 500 processors:

Engineering Advantages

• Non-Volatile Logic Security: The 1747-M1 utilizes EEPROM technology to store the controller's executive code and data. This eliminates reliance on the internal RAM battery, protecting your industrial process from logic erasure during long-term shutdowns.

• Rapid System Recovery: In the event of a processor fault or hardware swap, the 1747-M1 allows the new controller to auto-load the stored program. This "Plug-and-Play" recovery capability significantly reduces Mean Time to Repair (MTTR) in critical manufacturing environments.

• Deterministic Scan Performance: The module supports high-speed execution with a 0.9 ms program scan time and a 0.225 ms I/O scan time. This ensures that the addition of external memory does not compromise the high-speed response required for discrete control applications.

• Ultra-Compact Footprint: Weighing only 0.25 lbs, the module plugs directly into the processor’s internal memory socket. This internal mounting preserves valuable chassis slots for I/O modules while providing maximum data protection.

• Hardware-Based Code Protection: Once you burn the program to the 1747-M1, the module acts as a physical "Master Copy." This prevents unauthorized or accidental modifications to the active controller RAM from becoming permanent, maintaining the original validated logic state.

FAQs

• Does the 1747-M1 require an external power source to retain data?

  No. The EEPROM technology retains all stored data and instructions without any power. You can store this module on a shelf or inside an unpowered rack for years without losing the program.

• Which Allen Bradley processors support the 1747-M1 module?

  This module specifically supports the SLC 5/01 and SLC 5/02 modular processors, as well as several fixed SLC 500 controllers. Always verify the memory socket compatibility on your specific CPU before installation.

• What is the procedure for transferring a program to the 1747-M1?

  You must utilize the "Burn to EEPROM" command within your programming software (such as RSLogix 500). The processor transfers the contents of its active RAM to the 1747-M1 module for permanent storage.

• Is this a factory-sealed unit?

  Absolutely. We guarantee this 1747-M1 is 100% Brand New original hardware. It arrives in the original Allen Bradley factory-sealed anti-static packaging with the verifiable UPC (662073521648) intact.
