What it is and what it does
The Fuji Electric PXF4APR2-JVVA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That sampling rate means it catches fast thermal transients in processes like injection molding or packaging seal bars, where a slower loop would overshoot.
Where it fits
The 1/16 DIN (48 x 48mm) panel cutout is the standard footprint for temperature controllers across most OEM panels. Self-tuning means the PID loop auto-adjusts during startup — no manual gain tuning on the first run. Mounts in a standard panel cutout; wiring is per the terminal diagram on the housing.
