Summarize: 
ISO WZ Series is a mixed integrate circuit that thermal resistance signal as temperature high/low isolation converter to linearity standard signal to temperature. 
It integrated a set of isolated DC/DC converters, 
Linearization disposal and long line compensate circuit, can bring two group of each other isolated power to input port for magnifying circuit,
modulating circuit powered and output port demodulation. 
They can meet industrial wide temperature, humidity, shaky poor operation condition. 
ISO WZ Series temperatures signal isolation amplifier is very convenient, with minimal external components, can be realized Pt**0 RTD signal isolation transmitter. And can achieve the industrial site temperature control signal into two, into four functions.
