50 ms sampling in a 1/4 DIN package
The PXF9ACR2-MVVA1: That sampling rate means the controller reads the process variable and updates its output every 50 milliseconds — fast enough to catch thermal transients in injection molding barrels, packaging seal bars, or extrusion zones where a slower loop would let the temperature overshoot.
Panel fit and cutout
The 1/4 DIN form factor (96 x 96 mm panel cutout per DIN 43700) fits the standard panel opening used across most industrial temperature controller installations. The controller is compact enough for multi-zone panels where several units sit side by side — the 96 mm width leaves room for the wiring duct and terminal blocks between adjacent cutouts. Self-tuning means the controller automatically calculates PID parameters during initial heat-up, so the commissioning engineer does not need to manually tune the loop. For a process with a consistent thermal load profile, the auto-tune cycle converges within a few overshoot cycles.
