50 ms sampling — what it means for loop response
The PXF9APC2-FBCA1 samples the input every 50 ms. For a temperature loop with a dominant time constant of several seconds, that update rate adds negligible dead time — the controller sees a process change within one scan, so the PID output corrects before the error propagates.
Panel fit — 1/4 DIN footprint
Standard 1/4 DIN cutout (96 x 96 mm) — the controller slides into a panel cutout matching IEC 61554. The depth behind the panel accommodates the screw-terminal block and the internal power supply; no special clearance beyond the standard DIN envelope.
