What this controller is and what it does
The Fuji Electric PXF4ACE2-0VMA1 is a self-tuning 1/16 DIN (48 x 48 mm) temperature and process controller that samples the input every 50 ms — fast enough to catch thermal transients in a small reactor or oven zone before they overshoot. The 1/16 DIN panel cutout (45 x 45 mm) fits standard panel-mount enclosures; the 48 mm depth behind the panel leaves clearance for wiring ducts in shallow cabinets.
