50ms sampling in a 1/4 DIN footprint
The PXF9ACS2-0BCA1: That 50ms loop speed matters when you're controlling a fast-responding process like a small oven or a plastic extruder barrel zone — the controller sees a temperature upset and adjusts the output before the next cycle completes, rather than lagging by a full second and overshooting.
Panel fit and what the 1/4 DIN means
The 96 x 96mm face (1/4 DIN) is the standard cutout for temperature controllers across most panel builders' inventories — it drops into the same hole as older Fuji PXF and most competitive 1/4 DIN models. No need to enlarge the panel cutout or print a new gland plate if you're swapping out an older controller. The compact depth behind the panel frees up DIN rail space for the SSR or contactor bank feeding the heater load. For a multi-zone machine, the 1/4 DIN format stacks neatly in a row without crowding the terminal blocks below.
