6.4 Energy supply
The basic power supply for IO-Link devices is defined in the IO-Link
specification(https://io-link.com/share/Downloads/Package-2020/IOL-Interface-
Spec_10002_V113_Jun19.pdf).
Based on this, the following figure shows the principle of topology for the power
supply of the SREH-50-IOL smart rotary module.
Unlike shown in the simplified illustration, the connection between power
supplies and the SREH-50-IOL is usually made via an IO-Link master. This
topology is described in the section 6.3.3.
