The Fuji Electric PXF4AEY2-JBSA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed.
The 1/16 DIN (48 x 48mm) panel cutout is the standard size for compact controllers — it fits existing panel holes without adapter plates, and the 50ms sampling speed means the controller reads and updates the output every 50 milliseconds, fast enough for most thermal processes like plastic extrusion, packaging seal bars, and oven zones. Self-tuning means the controller automatically calculates PID parameters during the first heat-up cycle, so a commissioning engineer can skip manual tuning on most loads.
