What it is and what it does
The Fuji Electric PXF4APP2-JBKA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. It's a panel-mount instrument sized for the standard 1/16 DIN cutout, meaning it fits into the same slot as any other 48x48 controller — no panel rework needed when swapping in from another brand or an older Fuji model.
