The Fuji Electric PXF5AEP2-FVVA1 is a compact 1/8 DIN (48 x 96mm) temperature and process controller with a 50ms sampling speed and self-tuning capability. It is a current-production unit.
The 1/8 DIN form factor (48 x 96mm) is the standard panel cutout for a single-loop controller — it slides into the same hole as any other 1/8 DIN unit, so swapping in a failed controller from another brand is straightforward as long as the wiring and input type match. The 50ms sampling speed means the controller reads the sensor and updates its output every 50 milliseconds, fast enough for most thermal processes (ovens, extruders, packaging seal bars) but not for millisecond-critical events like injection mold cavity pressure. Self-tuning means the controller automatically calculates PID parameters during startup, saving the technician from manual loop tuning.
