The Fuji Electric PXF5ABS2-FVVA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
The 1/8 DIN (48 x 96mm) form factor fits the standard panel cutout used across the process industry — it drops into the same 45 x 92mm hole as other 1/8 DIN controllers, so swapping an older unit for this one usually requires no panel rework. The self-tuning algorithm automatically sets PID parameters on startup, which cuts commissioning time on a replacement controller: you wire the sensor and heater, power it up, and let it learn the thermal response.
