ET-R/I is the resistance change value of a potentiometer that uses an electric actuator as valve position feedback, which is converted into a 4-20mA DC valve position current signal output for indication and control of valve position opening. This actuator and its accessories are widely used in angular and linear electric actuators.
1、 Input:
If it is one of the 500 Ω~5K Ω potentiometers, the potentiometer used for valve position feedback in electric actuators is usually 1K. Please specify the resistance value of the potentiometer used when ordering.
2、 Output:
It is 4-20mA DC. Used for indication and control of valve position.
3、 Power supply:
Usually 220V, special requirements can be customized.
4、 Transformer dimensions:
The length, width, and height are 80 × 50 × 30mm
