Fuji Electric PXF9AER2-0VVA1, 1/4 DIN (96 x 96mm) self-tuning temperature and process controller, 50 ms sampling speed, current production.
The PXF9AER2-0VVA1: The 50 ms sampling speed means it updates the control output every 50 milliseconds — fast enough for thermal processes like extrusion barrel zones or reflow ovens where the time constant is in seconds, but not for sub-cycle power control.
It is a 1/4 DIN (96 x 96 mm) panel-mount controller with a 50 ms sampling speed. The self-tuning algorithm adjusts PID parameters automatically during the first heat-up cycle.
