XS-RTD RTD Input Isolator (Analog)

· 1 in 1 out, 1 in 2 out. Thermal resistance signal input. The output signal is 4~20mA or 0~20mA. Terminal supply or DIN rail power supply is available.
· XS-RTD Thermistor Input Isolator is a temperature transmitter that converts the field RTD resistance to a standard current signal. The RTD temperature transmitter is composed of analog circuit, has the advantages of no resolution error, no sampling period error, and also has important characteristics such as high reliability and no risk of crash.
· Output signal 4~20mA or 0~20mA
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
