Requirements for the power supply
External 24 V power supply
The MCU power supply is an external 24 V power supply (e.g.: SITOP). The following currents
that are drawn for an MCU provide a basis for calculating the 24 V DC power supply required.

2) MCU with full load at all outputs (digital outputs, USB, etc.)
Note
Inrush current
To start, the device requires an inrush current of at least 6.5 A for 15 ms.
The peak value of the starting current depends on the input voltage and the impedance of the
24 V DC power supply. Peak currents higher than 6.5 A are possible. This does not impair the
functionality of the device.
