Description:
ISO W-Z 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.
