The Fuji Electric PXR3-RAY2-GVTA1 is an advanced, self-tuning 1/32 DIN temperature and process controller that carries 16 ramp/soak segments for multi-step profiling. That 1/32 DIN footprint (roughly 24 x 48 mm) means it fits a standard panel cutout without eating up space — useful when you're packing multiple zones into a small enclosure. The self-tuning algorithm handles PID autotune on startup, so you don't need to manually calculate loop gains for each zone.
The 16 ramp/soak segments let you program a temperature profile — ramp up at a set rate, soak at a setpoint, then step to the next segment. That's what you need for curing ovens, reflow profiles, or heat-treat cycles where the process follows a recipe, not just a single setpoint. Self-tuning means the controller measures the thermal response of the load and sets its own PID coefficients; on a first power-up it'll overshoot once, then settle. If you're replacing an older 1/32 DIN controller, check the wiring — the PXR3 series uses a standard pinout for its form factor, but the input type (thermocouple, RTD, or analog) is set at ordering, so verify the sensor type matches what's in the field.
