Description
The YT-2550 Smart Valve Positioner accurately controls valve stroke according to an input signal of 4–20 mA, which is being input from the controller.
In addition, the built-in microprocessing operator optimizes the positioner's performance and provides unique functions such as auto-calibration, PID control, alarm, and Hart protocol.
