APPLICATION INFORMATION
Connection of Sensors (CT, Resistive Shunt)
Figure 28 and Figure 29 show how resistive dividers, current transformers, and restive shunts are connected to the voltage and
current inputs of the 71M6521DE/FE.

In the above formula T is the temperature in °C, N(T) is the ADC count at temperature T, Nn is the ADC count at 25°C, Sn is
the sensitivity in LSB/°C as stated in the Electrical Specifications, and Tn is +25°C.
