hello there ,
i’m having a trouble with an actuator (Chinese Actuator M8300 series) (http://www.cnzxq.com/products/Module/M8000/m8000_pcb.html) this link is for the circuit description.
the problem is that we need a (4-20ma) output from the actuator, and the board responsible for that didn’t come with the actuator. However, the actuator has a display screen that show the position of the valve in percentage .
the question is : can i get use of modifying the control circuit so i can get the value of the position and use it in external remote screen ?
i really wish that i can get an answer
thank you very much .
