The Fuji PXF5APP2-0BVA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed. The self-tuning algorithm handles PID autotuning on startup, so you don't need a laptop to commission it.
The 1/8 DIN form factor (48 x 96 mm panel cutout) is a standard slot size — slides into the same cutout as most Fuji PXF and PXG family controllers. If you're swapping an older unit, check the depth clearance behind the panel; the housing is roughly 100 mm deep including the terminal block. Spring-clamp or screw terminals depending on the suffix, but this order code's termination type isn't specified here — verify against the existing wiring before pulling the old one.
