Product Details
Product Overview
The Allen Bradley 1747-M13 serves as a specialized non-volatile storage solution for the SLC 500 controller platform. This 64 KB EEPROM (Electrically Erasable Programmable Read-Only Memory) module provides a permanent backup for user programs and data tables. It prevents costly downtime by ensuring the PLC retains its logic during extended power outages or battery failures. We supply this unit as 100% Brand New original factory stock, offering a vital lifeline for maintaining legacy SLC systems that require authentic, high-reliability components.

Engineering Advantages
-
Permanent Logic Safeguard: The 1747-M13 stores the entire processor memory image. In the event of a system-wide power failure or RAM corruption, the processor automatically reloads the program from this EEPROM module. This feature eliminates the need for manual intervention or a programming laptop to restore operations.
-
Rapid System Restoration: The module supports an "Auto-Load on Power-Up" configuration. When an SLC 500 processor detects a memory error, it pulls the verified 64 KB backup from the 1747-M13 in milliseconds, maintaining a 0.9 ms program scan time and restoring production immediately.
-
Seamless Hardware Integration: The module attaches directly to the SLC 500 processor’s internal socket. This board-level installation keeps the module protected within the processor housing, shielding it from electromagnetic interference (EMI) and physical vibration common in high-density rack environments.
-
Reliable Data Retention: Unlike standard RAM which depends on a lithium battery, the 1747-M13 uses EEPROM technology to hold data indefinitely without an external power source. This provides a long-term storage solution for remote or unmanned stations where regular battery maintenance is impractical.
FAQs
-
How do I transfer the program from the processor to the 1747-M13?
You must use RSLogix 500 software to initiate a "Burn to EEPROM" command. This process copies the current active program in the processor's RAM into the non-volatile cells of the M13 module.
-
Is the 1747-M13 compatible with all SLC 500 processors?
The 1747-M13 specifically fits processors with the internal memory module socket, such as the SLC 5/03, 5/04, and 5/05. Always check your specific processor's memory capacity to ensure the 64 KB limit accommodates your entire ladder logic and data table.
-
Does this module require a battery?
No. The 1747-M13 utilizes EEPROM technology, which does not require a battery to retain its data. It acts as the secondary backup precisely for when the primary processor battery fails.
-

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
