Product Description
This memory cassette provides non‑volatile program storage for MELSEC‑F FX3U series PLCs using flash memory technology. It offers a 16K steps program capacity and is designed to back up and transfer user applications between FX3U and FX3UC controllers without risk of battery loss. A protect switch supports write protection to prevent unintended overwrites in industrial environments. The unit is intended for field technicians and integrators needing reliable program retention during service, retrofit, or commissioning tasks. It is a plug‑in accessory engineered for compatibility with FX3U/FX3UC CPUs and conforms to major marine and EMC standards, ensuring suitability for harsh applications. Package contents typically include the memory cassette only; installation requires an FX3U/FX3UC base unit. The cassette is equivalent to model FX3UFLROM16, maintaining software consistency across the FX3U platform.
