8.3 Current consumption and power loss
Introduction
The DNP3 components obtain the current required for operation from an external power
supply. If the communications module TIM 3V-IE DNP3 is installed in an S7-300, it also
draws current over the S7-300 backplane bus.
You require the information on current consumption of the DNP3 components from the
external load power supply and from the backplane bus, for example, to configure the
cabinet for a DNP3 station.
Current consumption and power loss
The following table lists the current consumption and power loss of the DNP3 components
TIM and modem.
