The Fuji Electric PXF5AEY2-0VVA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
The 50ms sampling speed means this controller reads and updates its output every 50 milliseconds — fast enough for most thermal processes like injection molding, extrusion, or packaging heat-seal bars where overshoot needs to be caught quickly. The self-tuning algorithm adjusts PID parameters automatically on startup, so you don't spend commissioning time manually tuning a loop. The 1/8 DIN (48 x 96mm) form factor fits a standard panel cutout, common in retrofit or new-build control panels where space is tight but a full-size 1/4 DIN won't fit.
