GS8572-EX.RTD one in and out thermal resistance input isolation barrier
The isolation safety grid converts the thermal resistance signal in the field into the current signal or voltage signal, and transmits it from the danger area to the safe area.It can configure the measurement mark and range range through the computer.The product needs independent power supply, power supply, input and output three isolation.
