Convert 0~10V to the voltage of 4~20MA – electric current to change the circuit
Function of the circuit
In the form of voltage when the long distance transmits the analog signal, the resistance of signal source or D.C. resistance of the cable will cause the voltage to decay, the input of the end of signal receive is the lower in resistance, the voltage decays the more largely. Transmit the precision in order to improve, can adopt cycle
