Allen-Bradley 1784-SD1 1GB Secure Digital Memory Card

Product Dimensions：

The Allen-Bradley 1784-SD1 is a high-reliability, industrial-grade 1 GB Secure Digital (SD) Card manufactured by Rockwell Automation. It is specifically designed to provide non-volatile memory storage for Allen-Bradley Logix5000 controllers and industrial terminals.

Product Detailed Description

The 1784-SD1 is not a standard commercial SD card. It is engineered with specialized flash memory architecture (typically SLC – Single-Level Cell) to withstand the harsh environments of factory floors. Its primary function is to store controller projects (user program, tags, configuration), firmware history, and data logs, allowing for automatic project restoration in the event of a power failure or processor replacement.

Technical Parameters

Product Advantages

• Industrial Durability: Features superior temperature, shock, and vibration resistance compared to consumer-grade SD cards, preventing data corruption under extreme conditions.
• Automatic Recovery (Load on Power-Up): Allows a replacement PLC to automatically pull the user program from the SD card upon booting up, significantly reducing Mean Time to Repair (MTTR).
• Extended Write Endurance: Utilizes high-end flash management that handles significantly more read/write cycles, ensuring long-term data logging reliability.
• Native Integration: Fully recognized by Studio 5000 Logix Designer software, enabling easy backup, restore, and firmware upgrade paths directly from the development environment.

Important Considerations & Precautions

• Commercial Card Risk: While standard commercial SD cards may physically fit into the PLC slot, using them can cause intermittent communication errors, rapid card degradation, or failure to load during a critical power cycle.
• Safe Removal: Do not eject the 1784-SD1 card while the controller’s SD LED indicator is flashing (active read/write operations), as this can corrupt the file system.
• Write Protection Switch: The card features a mechanical write-protection slide switch on the side. Ensure it is unlocked (pushed upward toward the contacts) if the PLC needs to write data logs or project updates to the card.
• Formatting: If formatting becomes necessary, format the card using the recommended utilities within Studio 5000 or ensure it is formatted to standard industrial FAT specifications.

Product Applications

• Project Backup & Restore: Storing master copies of PLC application code for automated deployment without requiring a laptop or software license on the shop floor.
• Firmware Upgrades: Transporting specific controller firmware revisions to remote production sites for hardware updates.
• Data Logging & Recipe Storage: Saving process variables, alarm histories, or production recipes directly from the controller or an associated PanelView HMI terminal.
• Disaster Recovery: Acting as a localized safety vault so that if a controller takes a catastrophic electrical hit, the configuration is preserved on the card.
