Valve positioning loop — 50 ms sampling sets the update rate
This is a valve motor drive controller, not a general-purpose temperature controller — the 50 ms sampling speed is the critical loop-rate spec for positioning a valve actuator in a flow or pressure loop. The PXF5AVY2-FVUA1 fits 1/16, 1/8, and 1/4 DIN panel cutouts, so the same order code covers multiple form factors depending on the enclosure layout. The position feedback option (available on this variant) means the controller can close the loop on actual valve position, not just the drive command — useful for applications where hysteresis or backlash in the valve linkage would otherwise introduce positioning error.
