The Fuji Electric PXF4APA2-JBSA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. The self-tuning algorithm auto-adjusts PID parameters on startup, so you don't need to run a manual autotune cycle for each new heater load.
Panel integration
The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount size for compact controllers — fits the same hole as a Fuji PXR3 or a Yokogawa UT35. Depth behind the panel is tight; verify clearance for the terminal block and any optional communications cards before wiring.
