Overview
Thermocouple input temperature transmitter can isolate and convert
the DC signal from the thermocouple (TC) into a DC signal. This product
has a built-in cold junction compensation function and can be configured
intelligently. The actual range of the thermocouple can be set through
computer software. . It has the function of disconnection alarm and
out-of-range alarm function.
This product needs to be powered independently, and the power supply,
input and output terminals are isolated.
