Bus node power consumption
Load of the internal 5V power supply
The bus coupler is supplied with a built-in power supply unit which
provides the internal 5V power supply for the expansion modules from
the 24V power supply.
To determine the load of the internal 5V power supply the maximum
power consumption of every expansion module connected to it must
be added together.
The maximum load of the internal 5V power supply is 5 watts.
If the maximum load is exceeded expansion modules must be
removed from the bus node.
