AI Overview
Controllers with Valve Motor Drive (VMD) outputs, such as the West 6170+ or Fuji Electric PXG series, are designed for open-loop control of motorized valves by directly driving open/close actuators without needing a feedback potentiometer. They manage position-proportioning by calculating the required valve travel time, reducing actuator wear in industrial applications.
Key Features & Examples
- West 6170+ VMD Controller: A dedicated 1/16 DIN controller offering 3-point stepping (open/close) control.
- West 8170+ VMD Controller: Similar functionality to the 6170+ for 1/8 DIN applications.
- Fuji Electric PXG Series: Offers 1/16, 1/8, and 1/4 DIN options with PID control for motorized valves.
- Mechanism: These controllers use two relays (one for opening, one for closing) based on the calculated position demand, reducing valve oscillation.
