What the sampling speed means for loop tuning
The PXF9AEE2-JBCA1: A 50 ms sampling rate means the controller updates its PID calculation 20 times per second. For a fast-responding heater or a thin-film process where the thermal time constant is under a second, this lets the self-tuning algorithm converge on stable gains without overshoot — something a 1-second sample rate cannot do. The 1/4 DIN form factor (96 x 96 mm panel cutout) is the standard size for industrial temperature controllers, fitting the same cutout as legacy Fuji PXF and PXG series units. No panel rework needed if you are replacing an older 1/4 DIN controller.
Sourcing and compliance posture
Fuji Electric is the manufacturer. The controller falls under the Process / Temperature Controllers category.
