What this controller is
The Fuji Electric PXF5APA2-JBCA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
Integration notes
The 1/8 DIN form factor (48 x 96mm) fits a standard panel cutout. The 50ms sampling speed is the cycle time for the internal ADC and PID algorithm — not the output update rate, which follows the control loop period. Self-tuning means the autotune routine can be initiated on commissioning to set P, I, D parameters without manual calculation, useful when the thermal load characteristics are unknown.
