Right Answer:
The basic working principle of an I/P (Current to Pressure) converter is to convert an electrical current signal (typically 4-20 mA) into a proportional pneumatic pressure output. This pressure is then used to position the control valve. The positioner receives the pressure signal and adjusts the valve's position to ensure it matches the desired setpoint, providing precise control of flow or pressure in the system.
