Huaibei Huadian-Talking about the difference between passive isolator and active isolator
It is generally believed that signal isolators that can work without external power supply are passive isolators; active isolators require a special external power supply, such as 24VDC or 220VAC.

The difference between thermal resistance and thermocouple in Huabei Huadian Primary School
1. Signal type: The thermal resistance itself is a resistance signal. With the change of temperature, the resistance has a positive or negative resistance value change. The resistance signal is measured by the power supply excitation, so there is a hysteresis in the temperature transmission. Different conductors or semiconductors are connected into a closed loop. When the temperature at the two terminals is different, a thermoelectric potential will be generated in the loop, which will cause a change in the induced voltage, which will change with the change in temperature, and a directly measured voltage signal.
