The Fuji Electric PXF5ABS2-FBTA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed.
The 1/8 DIN form factor (48 x 96 mm panel cutout) fits standard DIN-rail or panel-mount enclosures. The 50 ms sampling speed is the key spec for loop tuning — expect to set the PID response time constants shorter than you would with a slower controller. Self-tuning simplifies commissioning on single-zone processes; manual override is still available for multi-zone or cascade loops where the autotune algorithm may fight adjacent zones.
