Allen Bradley 1747-M13 Detailed Product Introduction and Technical Specifications
Product Overview
The Allen Bradley 1747-M13 is a high-capacity EEPROM/Flash memory module designed for the SLC 500 programmable logic controller platform. It is used to store PLC programs and system data in a non-volatile format, ensuring that automation logic is preserved even during power loss or controller replacement.
This module is widely used in industrial automation systems that require reliable program backup, fast recovery, and long-term data retention.
Compared with smaller SLC memory modules such as 1747-M1 or 1747-M11, the 1747-M13 provides significantly larger storage capacity and broader compatibility with higher-end SLC processors such as SLC 5/03, SLC 5/04, and SLC 5/05 systems.
It is especially common in legacy industrial systems where long lifecycle stability and program portability are required.
