The Fuji Electric PXR3-AEY2-4V0A1 is an advanced, self-tuning 1/32 DIN temperature and process controller with 16 ramp/soak segments. The 1/32 DIN form factor (48 x 24 mm panel cutout) fits tight panel layouts where space is at a premium — common in reflow ovens, packaging seal bars, and single-zone lab ovens. The self-tuning algorithm auto-derives PID parameters during the first heat-up, saving commissioning time on processes with consistent thermal loads.
The 16 ramp/soak segments allow programming multi-step thermal profiles (heat, soak, cool cycles) without an external programmer — useful for curing, annealing, or soldering profiles. Self-tuning means the controller measures the process response and sets P, I, D values automatically, which reduces tuning time on a new oven or extruder barrel. The 1/32 DIN size limits the display and terminal density; verify your thermocouple type and output configuration (relay, SSR drive, or 4-20 mA) against the full model suffix before panel cutout.
