The PXF9ACA2-JVVA1: That sampling rate matters when you're chasing a fast-responding process like an extruder barrel zone or a small oven — the controller sees a temperature shift within a single mains cycle and can adjust the output before the next zero-cross, which keeps the process variable from overshooting the setpoint by more than a degree or two.
