The Fuji Electric PXF5ACE2-0VMA1 is a compact 1/8 DIN (48 x 96 mm) temperature and process controller with self-tuning and a 50 ms sampling speed.
The 1/8 DIN form factor (48 x 96 mm) fits the standard panel cutout used across the PXF series. Self-tuning simplifies commissioning on thermal processes with varying loads — the controller learns the system response during the first heat-up cycle and sets PID gains automatically. No manual tuning required unless you're chasing a very tight deadband.
