The Fuji Electric PXF4APE2-0BKA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. The self-tuning algorithm adapts PID parameters on the fly, so you don't need to run a separate autotune cycle on every startup.
Panel integration
The 1/16 DIN (48 x 48mm) cutout fits the standard panel-mount footprint shared by most compact controllers in this class. Depth behind the panel is typical for a single-board design, leaving room behind the gland plate for wiring. Spring-cage or screw terminals accept 0.2–2.5 mm² conductors; strip length of 8 mm avoids whiskers under the clamp.
