The Fuji Electric PXF5ACA2-0BCA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed. This form factor fits standard panel cutouts for single-loop control of heating or cooling processes — think ovens, furnaces, packaging seal bars, or plastic extrusion zones where the controller lives in a cutout, not on a DIN rail.
At 48 x 96mm (1/8 DIN), the controller occupies a single cutout in the panel door. Depth behind the panel is standard for this class — allow clearance for the screw-terminal block and any option cards. The self-tuning feature reduces the time a commissioning engineer spends on PID loop tuning, which matters when multiple zones on a machine all need individual controllers.
