The PXF4ABA2-FVJA1 is a self-tuning 1/16 DIN (48 x 48 mm) compact temperature and process controller from Fuji Electric's PXF series.
Sampling speed and what it means on the line
The 50 ms sampling rate is the headline spec here. Most 1/16 DIN controllers sample at 100–250 ms. This one updates the control output every 50 ms, which keeps the PID loop tight on fast-reacting loads like infrared heaters or thin-film processes. If you're replacing a controller that overshot on a 2-second heat cycle, this is the parameter that fixes it.
The 1/16 DIN (48 x 48 mm) form factor is the standard panel cutout for compact controllers. It snaps into the cutout with the mounting bracket supplied; no DIN rail required. The self-tuning algorithm auto-configures PID parameters on startup, so commissioning a new zone takes one cycle instead of manual tuning.
