DS-AT Thermocouple Input Isolator (Analog)

· 1 in 1 out, 1 in 2 out. Thermocouple signal input. The output signal is 4~20mA or 0~20mA. Terminal supply or DIN rail power supply is available.
· The DS-AT Thermocouple Input Isolator is a temperature transmitter that converts field thermocouple millivolts into a standard current signal. The product is composed of analog circuits, with no resolution error, no sampling period error, etc. It also has important characteristics such as high reliability and no crash risk.
· Output signal 4~20mA or 0~20mA
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
