Product Overview

The Allen Bradley 1784-CF128 serves as a high-reliability, non-volatile storage solution specifically engineered for the ControlLogix 5560 and L6 controller series. This 128 MB CompactFlash card provides the essential memory overhead required for complex data logging, recipe storage, and firmware backups. We supply this unit in 100% Brand New condition, ensuring maximum data integrity and industrial-grade longevity for your automation architecture.

Technical Specifications

This module utilizes a FAT 16 memory format to maintain high-speed data access and broad compatibility across the ControlLogix environment.

Engineering Advantages

• Data Integrity Protection: The non-volatile architecture retains critical system data even during total power loss, eliminating the risk of program erasure.

• Advanced File Management: The card supports sophisticated secondary functions including checksum calculations and error handling. These features verify data accuracy during file transfers, preventing corrupted parameters from reaching the processor.

• Optimized for L6 Architecture: Unlike standard consumer-grade CF cards, the 1784-CF128 handles specific industrial tasks such as data parsing and file printer settings natively within the ControlLogix environment.

• Lightweight & Secure: At only 0.03 kg, the module adds negligible mass to the controller assembly while the robust internal flash memory resists the vibrations typical of industrial cabinets.

FAQs

• Does the 1784-CF128 support Removal and Insertion Under Power (RIUP)?

  No. You must power down the controller or ensure the system is in a safe state before inserting or removing the card. Handling the card while the controller is active may lead to data corruption or hardware faults.

• Can I use this card with the newer ControlLogix 5570 or 5580 series?

  The 1784-CF128 specifically supports the ControlLogix 5560 (L6) series. Newer controllers typically utilize Secure Digital (SD) cards rather than CompactFlash. Always verify the physical slot type on your controller faceplate before purchase.

• What is the maximum number of files I can store?

  The FAT 16 formatting on this card supports a maximum of 250 files. It manages one open file at a time, ensuring focused processing power for read/write operations.

• Is this product an aftermarket equivalent?

  No. We provide only original, Brand New Allen Bradley units. Using genuine 1784-CF128 cards ensures full access to checksum verification and error-handling protocols that generic cards often lack.
