The PXF4ACU2-GBYA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed — fast enough to catch thermal overshoot on injection-molding barrel zones or extrusion heaters before the process drifts. That 50ms update rate means the PID loop corrects on every half-cycle of a 50/60 Hz line, so you get tighter regulation than a standard 100ms or 250ms controller on fast-responding electric heaters.
Panel Integration
The 1/16 DIN (48 x 48mm) cutout matches standard panel-mount controllers. Depth is shallow enough for shallow enclosures; allow clearance behind the panel for the screw-terminal block and any optional communication module. The self-tuning algorithm runs on startup or on demand, so commissioning is a single setpoint entry — no manual PID gain calculation.
