The PXF4ACY2-FVKA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That 50ms update rate means it catches fast thermal transients in processes like injection molding or small furnace zones where a standard 100ms or 250ms controller would lag behind the actual temperature curve.
The 1/16 DIN (48 x 48mm) panel cutout is the standard footprint for this controller class — fits existing panel punches without adapter plates. The self-tuning algorithm eliminates manual PID gain scheduling during commissioning; it auto-tunes on startup or on demand.
