Fuji Electric PXF series valve motor drive controller, PXF4ATY2-0V1A1, 1/16 to 1/4 DIN formats, 50 ms sampling, position feedback option.
Position feedback option available. The 50ms sampling speed enables closed-loop control for modulating valves. Confirm form-factor compatibility — the PXF4ATY2-0V1A1 fits 1/16, 1/8, and 1/4 DIN openings, so check your panel punch-out and depth clearance before specifying.
The controller updates its output every 50 ms, which is fast enough for most modulating valves in flow/pressure loops. Combined with the position feedback option, you get closed-loop response at that rate without additional external PID.
