The Fuji Electric PXF4ABY2-JVJA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed.
The 1/16 DIN (48 x 48mm) panel cutout is the standard small-footprint size for temperature controllers, fitting the same panel hole as hundreds of other 1/16 DIN units — so a swap-in replacement for an existing controller of this form factor is straightforward, provided the wiring and input/output types match. Self-tuning means the controller automatically calculates PID parameters during initial heating, reducing commissioning time compared to manually tuning a loop — useful when the same spare is dropped into different machines with different thermal loads.
