The PXR3-AEC2-5BTA1 is a 1/32 DIN temperature and process controller from Fuji Electric's PXR3 series, featuring self-tuning and 16 ramp/soak segments for multi-step thermal profiling. Its compact form factor fits tightly packed panels where every millimeter of DIN rail counts — the 1/32 DIN cutout (45 x 22.5 mm) is the smallest standard size, so plan your gland plate and wiring duct clearance accordingly.
Self-tuning means the controller automatically adjusts PID parameters during the first run, eliminating manual loop tuning for most processes. The 16 ramp/soak segments allow programming a multi-step profile — useful for curing ovens, reflow soldering, or any thermal cycle that needs controlled heating and cooling rates. As a 1/32 DIN unit, it fits a 45 x 22.5 mm panel cutout; the small face limits display readability at distance, so mount it where an operator can read the 4-digit LED without squinting.
