Fuji Electric PXF9ACY2-JBCA1 1/4 DIN Temperature Controller

50 ms sampling, self-tuning loop

The PXF9ACY2-JBCA1: It samples at 50 ms and includes a self-tuning algorithm — that sampling rate catches thermal transients a 100 ms or 200 ms controller would alias, so you can tune a fast-responding electric heater or a thin-film oven without overshoot hunting.
