The picture shows the DC isolation servo amplifier circuit. When the analog signals are mixed with mode voltage noise, you can use this circuit to make the sensor input signals impend. In order to transmit the DC signal, the circuit uses servo means to form a feedback circuit to improve the stability of the circuit. A1 uses constant current drive optocoupler HP2731 in the light-emitting diode, the input signal bias current is 4mA. The optocoupler in the circuit uses double-type circuit HP2731. It has tracking performance.
