What the sampling speed buys you
The PXF9ABS2-0BCA1: A 50 ms sampling interval means the controller updates its PID output every two mains cycles at 50 Hz — fast enough to regulate electric heater banks or small infrared ovens without overshoot on the first thermal time constant. The self-tuning algorithm auto-adjusts P, I, and D gains on startup, so you do not need a separate autotune cycle or manual Ziegler-Nichols step test during commissioning.
