A hybrid integrated circuit that converts the power frequency AC signal (50-60HZ) output by the power grid and motor detection sensor into a linearly changing analog DC signal. The 0-1Vrms power frequency AC signal collected by the sensor can be proportionally converted into a 4-20mA or 0-5V DC signal. Through the external AC voltage mutual inductance, a single-phase or multi-phase isolation transmitter can be formed to achieve three isolations between the input and output signals and the auxiliary power supply. The product is widely used in the fields of generator or motor safe operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal transmission and reception, industrial automation control, etc.
