Application Information
3.1
Connection of Sensors
Figure 28 through Figure 30 show how resistive dividers, current transformers, Rogowski coils and resistive
shunts are connected to the voltage and current inputs of the 71M6531.
The analog input pins of the 71M65XX are designed for sensors with low source impedance. RC
filters with resistance values higher than those implemented in the Teridian Demo Boards should be
avoided.

Connecting 5-V Devices
All digital input pins of the 71M6531D/F and 71M6532D/F are compatible with external 5-V devices. I/O
pins configured as inputs do not require current-limiting resistors when they are connected to external 5 V
devices.
