The PXF5APA2-MBVA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller from Fuji Electric, with a 50ms sampling speed. The self-tuning algorithm sets PID gains on first power-up, so you don't need a laptop to commission it.
The 1/8 DIN footprint (48 x 96mm) fits a standard panel cutout — no adapter frame needed. For a panel wireman, that means it slides into the same hole as any other 1/8 DIN controller; the depth is tight on shallow enclosures, so check behind-panel clearance before routing conduit.
