The PXF5APR2-FBVA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with 50ms sampling speed.
The 1/8 DIN form factor fits standard panel cutouts, so swapping in a failed unit or adding a zone to an existing line doesn't require reworking the enclosure. Self-tuning simplifies commissioning: the controller learns the process dynamics on startup and sets PID gains without manual bump tests.
