The PXF4ACR2-MV1A1 is a self-tuning 1/16 DIN (48 x 48 mm) compact temperature and process controller with a 50 ms sampling speed. That sampling rate means the controller updates its output every 50 milliseconds, which is fast enough for most thermal loops in extrusion, packaging, or HVAC — not for sub-cycle arc or fast-moving web processes, but well within the response time of thermocouple-based temperature control.
The 1/16 DIN (48 x 48 mm) panel cutout is the standard footprint for this class of controller. It snaps into a panel cutout without extra hardware; the depth behind the panel is typically around 100 mm, so verify clearance inside the enclosure before wiring. The 50 ms sampling speed is the update interval for the input measurement — the output update rate may be slower depending on the PID algorithm and output type.
