50 ms loop — fast enough for thermal, not for pressure
The PXF9AES2-0BCA1 is a self-tuning 1/4 DIN (96 x 96 mm) temperature and process controller with a 50 ms sampling speed — that's a 20 Hz update rate, which catches thermal transients in reflow ovens and extruder zones but won't track a pressure spike or a fast-flow valve stroke.
Lifecycle read — still a current line item
For a BOM-freeze or MRO planner, that means no urgency to qualify a substitute — the supply channel is the standard distribution route, not surplus or broker.
Panel fit — 1/4 DIN cutout, no surprises
The 96 x 96 mm face and 1/4 DIN cutout are standard across the panel-instrument class — the controller slides into the same hole as any other 1/4 DIN indicator or recorder, so a swap doesn't require re-punching the panel. The 50 ms sampling rate means the PID loop updates faster than the typical 100–200 ms scan of a PLC analog input, so the controller handles the closed-loop tuning itself rather than relying on the PLC's cycle time.
