The Fuji Electric PXF5AEC2-FVCA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed.
The 1/8 DIN form factor (48 x 96 mm) fits a standard panel cutout; the compact depth leaves room behind the door for wiring terminations and a back-of-panel terminal block. Self-tuning reduces commissioning time on thermal loops — the controller learns the process dynamics rather than requiring manual PID gain scheduling.
