Details

DSA-AT thermocouple input barrier (analog type)

1 in 1 out, 1 in 2 out. Thermocouple signal, intrinsically safe input. Terminal supply or DIN rail power supply is available.

· The DSA-AT Thermocouple Input Barrier is a temperature-transfer isolation barrier that converts the field thermocouple millivolts to a standard current. The thermocouple input isolation safety barrier is composed of analog circuits, has the advantages of no resolution error, no sampling period error, and has high reliability, no crash risk and other important characteristics.

· Output signal 4~20mA or 0~20mA

· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
