Hi, Dear! Welcome to our online store...
XSA-RTD Thermal resistance input barrier (analog type)
· 1 in 1 out, 1 in 2 out. Thermal resistance signal, intrinsically safe input. Terminal supply or DIN rail power supply is available.
· XSA-RTD Thermistor input barrier is a temperature-transfer isolation barrier that converts the resistance of the field RTD to a standard current. The thermal resistance input isolation safety barrier is composed of an analog circuit, and has the advantages of no resolution error, no sampling period error, and the like, and has high reliability, no crash risk and the like.
· Output signal 4~20mA or 0~20mA
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
