What the 50ms sampling buys you on a hot bearing
The PXF9ACA2-0BCA1: The 50 ms sampling speed means it catches thermal transients on a hot bearing or a fast-ramping oven before the process drifts out of band — not all controllers in this footprint sample that fast.
Panel fit and what the 1/4 DIN means
The 1/4 DIN cutout (96 x 96 mm) is a standard panel-mount footprint across most controller brands. No special adapter plate needed for a standard panel cutout — it slides into the same hole as any other 1/4 DIN instrument.
