50 ms sampling — what it buys on a real process loop
The 50 ms sampling speed on this Fuji Electric PXF9APA2-JVMA1 means it can track temperature swings in fast-responding processes — think thin-film extrusion, injection mold cavity temps, or small-batch reactors where a 200 ms update rate would alias the thermal transient. That 50 ms figure is the controller's A/D conversion and PID compute cycle combined, so the output updates at 20 Hz. For a 1/4 DIN panel-mount unit, that speed is unusual; most mid-range process controllers sample at 100 ms or slower.
Panel cutout and retrofit fit
The 1/4 DIN form factor means a 96 x 96 mm panel cutout — the standard for process controllers across all major brands. Depth is typically 100-110 mm behind the panel for the terminal block and power supply. If you're swapping out an older Fuji or a Yokogawa/Omron unit, the same hole saw works. No DIN-rail adapter needed; the controller clamps into the panel with the included bracket.
