The FX3U-FLROM-16 is a Flash-RAM memory cassette for Mitsubishi's FX3U series PLCs. It stores the program and device comments, with a maximum capacity of 16000 steps. This is the memory module you slot into the FX3U CPU to hold the logic that keeps the kiln sequence stable — no program, no clinker. Flash memory means the program is retained without battery backup. Rated for 10000 write cycles, so it's built for the occasional program update, not for continuous data logging. The PROTECT switch prevents accidental overwrites once the program is final — a hard-wired guard against a junior tech's midnight edit.
