Hi, Dear! Welcome to our online store...
XSA-ZT thermal resistance or thermocouple input isolation barrier (smart type)
· 1 in 1 out, 1 in 2 out, suitable for RTD or thermocouple temperature sensor, intrinsically safe input. The settings can be configured. 0/4~20mA output. Terminal supply or DIN rail power supply is available.
· XSA-ZT is suitable for the input of the RTD or thermocouple signal in the hazardous area of the field. After isolation, it is converted into a standard current signal output to the safety zone control system or other meter.
· Switch the thermocouple and thermocouple input signals according to different wiring methods. Input signal type or range can be configured via software.
· Output signal 4~20mA or 0~20mA.
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
