50ms sampling on a 1/4 DIN loop controller
The PXF9ABA2-JV1A1: At 50ms per sample, the PID loop updates at 20 Hz, which means the controller can respond to a thermocouple step change within one mains cycle on a 50 Hz line. That matters when the process gain is high and the alternative is a 250ms-sampling controller that lets the temperature coast past the setpoint.
