Siemens SINAMICS S120 Manual page 233

Direct encoder systems outside the cabinet can be connected to the Sensor Modules External.
The Sensor Modules External evaluate these encoder systems and convert the calculated values
to DRIVE-CLiQ. No motor or encoder data is stored in the Sensor Modules External.
Note
The Sensor Module External provides the encoder power supply. The power supply for the
Sensor Module External is provided from the connected DRIVE-CLiQ cable. This fact must be
taken into consideration when the DRIVE-CLiQ cable is selected.
The Sensor Modules External have a higher degree of protection (IP67) and are therefore
suitable for installation outside the cabinet.
