3.3 Current consumption and power loss of the SINAUT ST7 components
Introduction
The SINAUT ST7 components obtain the current required for operation from an external
power supply. If the communications module TIM 4 or a TIM 3V-IE variant 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 SINAUT ST7 components from
the external load power supply and from the backplane bus, for example, to configure the
cabinet for a SINAUT ST7 station control device.
Current consumption and power loss
The following table lists the current consumption and power loss of the SINAUT ST7 TIM
and modem components.
