Allen Bradley 1747-M13 EEPROM Memory Module

Product Introduction

The Allen-Bradley 1747-M13 EEPROM Memory Module is a high-capacity non-volatile memory module designed for SLC™ 500 programmable controller systems. It is used to store and preserve user application programs, system configuration data, and control parameters, ensuring reliable program retention and fast recovery in demanding industrial environments.

With a 64 KB memory capacity, the 1747-M13 is suitable for larger and more complex control applications that involve extensive logic, structured routines, and significant I/O interaction. The module enables automatic or manual restoration of programs to the processor, significantly reducing downtime during controller replacement, power restoration, or maintenance activities.

In addition to program storage, the 1747-M13 supports systems with large chassis configurations, making it an ideal choice for multi-rack SLC 500 installations where system scalability and stability are critical.
