The Fuji Electric PXF4AEA2-JBVA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. The self-tuning algorithm auto-derives PID constants on first run, so commissioning is a setpoint-and-walk-away job on most thermal loads.
The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount footprint for temperature controllers — fits the same hole as every other 1/16 DIN unit on the market, so no panel rework if swapping from another brand. Depth is compact enough for shallow enclosures; no DIN-rail adapter needed since it's panel-mounted with the included bracket.
