FX3U-FLROM-16 MISTUBISHI 16K Step Flash Memory Cassette

The FX3U-FLROM-16 MISTUBISHI (Model: FX3U-FLROM-16) is a reliable non-volatile flash memory cassette engineered specifically for Mitsubishi Electric MELSEC FX3U and FX3UC Series compact PLCs. Providing 16,000 steps (16K steps) of program memory capacity, the FX3U-FLROM-16 MISTUBISHI allows system integrators and panel builders to store PLC programs, symbol comments, parameter blocks, and control logic directly on removable memory hardware.

By plugging directly into the front memory socket of FX3U CPU base units, the FX3U-FLROM-16 MISTUBISHI prevents program loss during extended cabinet power outages or battery failures. It also provides a hardware write-protect switch to shield critical application routines from unauthorized field modification and simplifies OEM machine program cloning.

Key Features of the FX3U-FLROM-16 MISTUBISHI

• 16K Step Flash Memory: Expands non-volatile program storage up to 16,000 steps for small-to-medium PLC applications and parameter sets.

• Battery-Independent Storage: Non-volatile flash technology retains application code permanently without relying on internal RAM backup batteries.

• Direct CPU Socket Installation: Snaps directly into the dedicated memory slot under the FX3U front cover without mounting tools or wiring.

• Hardware Write-Protection Switch: Integrated lock switch prevents accidental program overwrites, field clearing, or unauthorized alterations.

• Fast OEM System Replication: Enables rapid loading and duplication of standardized machine code across production panels.

• Direct Program Execution: Supports program loading, execution, and uploading directly through the FX3U CPU memory bus.

Primary Applications

• OEM Machine Replication: Standardizing and loading control programs across series-produced packaging and assembly machinery

• Marine & Remote Telemetry Panels: Ensuring zero program loss during long-term shipboard power shutdowns or remote maintenance

• Industrial Process Control: Storing core operational logic, alarm thresholds, and positioning parameters securely on hardware
