RTD Isolated Signal Isolated Converter / RTD Temperature Transmitter for Ground Interference Suppression

ISO W-Z Series temperatures signal isolation amplifier is very convenient, with minimal external components, can be realized Pt100 RTD signal isolation transmitter. And can achieve the industrial site temperature control signal into two, into four functions.

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.

Applications:

● Temperature signal isolation, acquisition and transfer

● Power monitoring, medical equipment, temperature control isolation barrier

Specifications:

● Three-wire, four-wire or two-wire PT100/Cu50 thermal resistance signal input

● Accuracy, Linearization error grade:0.2(Relative Temperature)

● Built-in linear processing and long-term compensation circuit

● Isolation Voltage: 3000VDC  Three port: input/power/output

● Auxiliary Power Supply:5V,12V,15V or 24VDC

● International standard signal output:4-20mA/0-5V/0-10V etc

● Small size, low cost, easy use and high reliability

● Standard DIP 24/SIP12 Pin, UL94V-0 package

● Industrial temperature range: - 45℃ ~ + 85 ℃
