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 71M6521BE.

Connecting 5V Devices
All digital input pins of the 71M6521BE are compatible with external 5V devices. I/O pins configured as inputs do not require
current-limiting resistors when they are connected to external 5V devices.
See the cautionary note on the restrictions for combined SEG/DIO pins configured as digital inputs in the Digital I/O
Section.
