The Fuji Electric PXF5ABA2-FBTA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50 ms sampling speed.
No official successor or replacement is indicated; the PXF5ABA2-FBTA1 is the current offering for this form factor and speed class.
The 1/8 DIN (48 x 96mm) panel cutout is a standard size across temperature controller families, so swapping into an existing panel hole typically requires no additional adapter plate. Self-tuning simplifies commissioning: the controller learns the process dynamics on startup and sets PID gains automatically, reducing manual tuning time on the line.
