Allen-Bradley 1784-SD1 1GB High-Speed SD Storage Card

Product Overview

The ALLEN-BRADLEY 1784-SD1 is a high-reliability Secure Digital (SD) card featuring a 1GB storage capacity. Specifically engineered for use with Allen-Bradley Logix5000™ controllers and other automation hardware, this card provides a ruggedized solution for non-volatile memory storage. Whether used for firmware updates, project backups, or data logging, the 1784-SD1 ensures that critical system parameters are preserved even during power loss. Its ultra-lightweight design weighs approximately 0.04 kg (0.09 lbs), making it a standard yet essential component for modern control architectures.

Technical Configuration

Reliability & Performance

Unlike commercial-grade flash media, the 1784-SD1 is built to withstand the rigorous demands of factory environments. It features an optimized operating temperature range of 0°C to 60°C (32°F to 140°F), ensuring consistent data accessibility in unconditioned control panels. The card’s high-speed data transfer rates minimize the time required for program loading and system boots, enhancing overall plant floor efficiency. With a net weight of only 0.04 kg, it provides high-density storage in a minimal form factor.

Data Security & Integration

The 1784-SD1 serves as a secure vault for user programs and sensitive application data. By storing a secondary copy of the controller project on this flash card, maintenance teams can quickly restore system operation after a hardware replacement without needing a laptop or network connection. Its seamless compatibility with Rockwell Automation hardware ensures that there are no integrity issues during high-speed read/write cycles.

Technical Specifications

Operational Advantages

• Program Portability: Easily transfer controller projects from one chassis to another by simply swapping the SD card.
• Maintenance Efficiency: Eliminates the need for manual program re-loads after a power failure if the controller is configured to "Load on Power Up."
• Vibration Resistant: Unlike traditional mechanical storage, the solid-state 1784-SD1 is highly resistant to shock and vibration.
• Firmware Management: Simplifies the process of updating or reverting controller firmware in the field.

Technical FAQs

Q1: Can I use a standard commercial SD card instead of the 1784-SD1?
A1: While a standard card may fit, it is not recommended. Automation-grade cards like the 1784-SD1 are rated for higher write cycles and wider temperatures to prevent data corruption.

Q2: How do I load the program from the card to the controller?
A2: Within Studio 5000 software, you can configure the "Non-Volatile Memory" tab to load the image "On Power Up" or "On Corrupt Memory."

Q3: Is 1GB enough for complex projects?
A3: Yes, 1GB is more than sufficient for the vast majority of Logix-based control programs, including documentation and HMI tag databases.
