Fast loop for thermal processes
The PXF9ACY2-FVVA1: The 50 ms sampling means the PID loop updates every cycle of a 50 Hz mains waveform, so it can respond to load changes before the process drifts outside the deadband.

Fuji Electric PXF9ACY2-FVVA1, 1/4 DIN (96x96mm) compact temperature and process controller, self-tuning, 50ms sampling speed.

The controller samples at 50 ms — this is the loop update rate for the self-tuning PID algorithm. It is fast enough for most thermal processes like extruder barrels, hot-runner manifolds, and diffusion furnaces.
