The PXF4AES2-MVMA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed.
The 1/16 DIN (48 x 48mm) panel cutout is the standard small-controller footprint — it fits the same 45 x 45mm panel opening as every other 1/16 DIN controller on the market, so a swap into an existing panel cutout requires no rework. The 50ms sampling speed is the cycle time at which the controller reads the input and updates the output; for processes with thermal time constants under a few seconds (thin-film heaters, small extruder barrels, lab ovens), that speed provides tighter overshoot control than a 100ms or 200ms controller.
