The PXF4ATY2-0BDA1 is a current-production valve motor drive controller from Fuji Electric, designed to drive 1-phase or DC valve motors with a sampling speed of 50 ms and an available position feedback option. It fits standard 1/16, 1/8, or 1/4 DIN panel cutouts, making it a direct drop-in for existing valve positioner installations or new builds requiring closed-loop control.
Sampling speed and position feedback
The 50 ms sampling cycle sets the controller's update rate for valve position feedback and output corrections. For proportional valves, this is fast enough to manage typical industrial process loops — think flow or pressure control — where sub-second response is adequate. The position feedback option, if fitted, closes the loop around the valve stem or actuator position, which is critical for repeatability in applications like burner management or mixing valves. 50 ms sampling updates valve position correction. Position feedback is optional.
