The PXR3-AAC2-4B0A1 is a 1/32 DIN temperature and process controller from Fuji Electric's PXR3 series, carrying self-tuning PID logic and 16 programmable ramp/soak segments for thermal profiling. The self-tuning feature means the controller automatically calculates PID coefficients during the first heat cycle, so an integrator can commission a zone without manual loop tuning — useful when the thermal load changes between production runs. Sixteen ramp/soak segments let the controller execute multi-step temperature profiles (e.g., preheat, hold, ramp-down) without an external PLC or sequencer, which saves a digital output and a programming step on the machine controller.
Deployment context
The 1/32 DIN form factor (48 × 24 mm panel cutout) fits into crowded control panels where space is tight — common in packaging machinery, laboratory ovens, and small-scale process skids. Because it is a panel-mount controller, the wiring terminates at the rear screw terminals; plan for a minimum of 100 mm clearance behind the panel for finger-safe access during commissioning.
