3.24.6.2 Calculating the internal I/O power consumption of the X20BR9300
The I/O summation current of all I/O modules supplied by the X20BR9300 is needed to calculate the internal I/O
power consumption. The I/O summation current is composed of three parts:
•
Internal power consumption of the I/O modules
•
Sum of the output currents
•
Sum of the actuator currents
Internal power consumption of the I/O modules
The current that results from the internal consumption of the I/O modules is calculated according to the following
formula:
Sum of output and actuator currents
Two X20DO4322 modules are included in the example configuration. The following images show which outputs
are wired and how high the output current and actuator current are per channel.
