The PXF5ACP2-FBTA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
The 1/8 DIN form factor (48 x 96mm) is a standard panel cutout — fits the same hole as most competitive 1/8 DIN controllers, so a panel retrofit doesn't require re-punching. The 50ms sampling speed is the cycle time at which the controller reads the input and updates the control algorithm; for slow processes like oven or furnace control, a slower 100ms or 250ms controller would work fine, but this one handles faster loops like extruder barrel zones or packaging heat-seal bars.
