Fuji Electric PXF5ABC2-MV1A1 Temperature Controller, 1/8 DIN

The PXF5ABC2-MV1A1: The 1/8 DIN form factor (48 x 96mm) is the standard panel cutout for a temperature controller — it drops into the same hole as every other 1/8 DIN unit, so swapping an older controller for this one is a straight mechanical fit. Self-tuning means the autotune algorithm runs on startup to characterize the thermal loop — it sets PID gains automatically, saving the commissioning engineer from manual tuning on a live line.
