PHG-11TT Series PHG-12TT series
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.
