Example:
Calculating the current consumption on an example coupler
Internal current consumption
Residual current for bus modules
Sum I
(5 V) total
The internal current consumption is indicated in the technical data for each bus
terminal. In order to determine the total requirement, add together the values of
all I/O modules in the node.
Please note the aggregate current for I/O modules. It may be necessary to
supply potential!
When the sum of the internal current consumption for the I/O modules exceeds
their aggregate current, you must use a supply module with bus power supply.
Install it before the position where the permissible aggregate current would be
exceeded.
Example:
Calculating the total current on the example coupler
A node with an example coupler consists e. g. of the following I/O modules:
20 relay modules (750-517) and 10 digital input modules (750-405).
Internal current consumption
Sum
In this example, the example coupler can provide 700 mA for the I/O modules.
This value is given in the associated data sheet ("Total current for I/O modules").
Consequently, an internal system supply module (750-613), e. g. in the middle of
the node, should be added.
The maximum input current of the 24 V system supply is 500 mA. The exact
electrical consumption (I
300 mA at 5 V
700 mA at 5 V
1000 mA at 5 V
10 * 90 mA =
20 * 2 mA =
) can be determined with the following formulas:
