The Fuji Electric PXR3-REE2-5B0A1 is an advanced 1/32 DIN temperature and process controller that handles up to 16 ramp/soak segments and includes self-tuning for the PID loop — meaning it learns the thermal response of the oven, kiln, or process vessel and sets its own gains without a technician stepping through a manual autotune cycle. This is a panel-mount controller in the compact 1/32 DIN format, so it fits a 48×24 mm cutout and leaves room on the panel for additional instruments.
The 16 ramp/soak segments let you program a multi-step temperature profile — for example, a solder reflow curve with preheat, soak, reflow, and cool-down stages — without an external programmer. The self-tuning algorithm measures the process response during startup and adjusts the P, I, and D terms automatically, which saves commissioning time on a new oven or when the thermal load changes.
