What the Ratings Mean
The PXF5ACS2-FBTA1: The 50ms sampling speed means the controller updates its PID output every 50 milliseconds — fast enough for thermal processes like injection molding or furnace zones where overshoot matters, but not intended for sub-cycle power control. The 1/8 DIN form factor (48 x 96mm) fits standard panel cutouts; verify gland-plate clearance if retrofitting into a densely packed enclosure.
