128 MB non-volatile memory Industrial SLC NAND flash High endurance and temperature resilience Automatic load on power-up Supports program storage, firmware upgrades, and data logging

Product description

The Allen-Bradley 1784-CF128 is an industrial-grade, 128 Megabyte CompactFlash (CF) memory card designed for ControlLogix and CompactLogix programmable logic controller (PLC) families. It utilizes Single-Level Cell (SLC) NAND flash memory for high endurance and resilience in harsh industrial environments, withstanding more read/write cycles and extreme temperature fluctuations.

This memory card serves as a robust, non-volatile storage solution, ensuring that user programs, tag data, and firmware configurations are permanently backed up. It can be configured for automatic program loading upon system power-up, guaranteeing that even with a failed internal battery, the machine boots with the correct program. It also provides ample space for controller firmware files, enabling rapid, laptop-free firmware flashing.
