The Fuji Electric PXF4APP2-JBSA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed.
The 1/16 DIN form factor (48 x 48mm panel cutout) is the standard compact controller footprint — it drops into the same panel hole as any other 1/16 DIN unit, so a retrofit or a new panel layout uses the same punch. The self-tuning feature means the PID coefficients are calculated during the first heat-up cycle; no manual gain tuning for a simple oven or bath.
