1/4 DIN form factor with high-speed loop
The PXH9F201-BV000: The 1/4 DIN cutout (92 x 92 mm panel opening) is the standard for standalone controllers that need a readable display and space for terminal blocks behind the panel — it fits existing panel cutouts without adapter plates.
What the high-speed rating means for the loop
High-speed and high-performance in a process controller typically refers to a fast sampling rate (often 50 ms or faster) and a PID algorithm that can handle rapid temperature excursions — useful for plastic extrusion, packaging seal bars, or any thermal process where overshoot and settling time matter more than absolute accuracy at steady state.
This is a current-production Fuji Electric part.
