The Fuji Electric PXF5ABR2-JBCA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed. This puts it in the fast-loop category for thermal processes where overshoot on startup or load changes needs to be minimized without manual PID tuning.
The 1/8 DIN (48 x 96mm) panel cutout is a standard footprint shared across many temperature controllers, so panel retrofits or drop-in replacements are straightforward. The 50ms sampling speed is fast enough for most electric heater and oven control loops; for very fast thermal processes (e.g., infrared heaters or thin-film deposition), a controller with sub-10ms sampling would be needed.
