Principle

This SVi1000 Digital Valve Positioner supports HART® communications over the 4-20mA signal, making it a superior choice for control systems with 4-20mA signaling.
The SVi1000 is a smart electro-pneumatic positioner that receives a 4 - 20 mA electrical position setpoint signal from the controller and compares the position setpoint input signal to the valve position feedback sensor. The difference between the position setpoint and position feedback is analyzed by the position control algorithm that sets a servo signal for the I/P converter. The output pressure of the I/P is amplified by a pneumatic relay that drives the actuator. Once the error between the setpoint and the valve position feedback is within range, no other correction is applied to the servo signal in order to maintain valve position. The local user interface and LEDs provide configuration or calibration mode in all operating environments.
The SVi1000 Positioner (see Figure 1 on page -9) is suitable for installation indoors or outdoors.
