Supply voltage of the module logic

4.3 Supply voltage U
For the operation in an IndraControl S20 station, the module is integrated be‐
hind a Sercos S20 bus coupler (S20-S3-BK+).
For detailed information on the setup of an IndraControl S20 sta‐
tion, refer to the application description of the IndraControl S20
system R911335988
WARNING
For the voltage supply at the bus coupler, use only voltage supplies acc. to
EN 50178/VDE 0160 (PELV).
Ensure that the output voltage of the voltage supply for the bus coupler does
also not exceed 30.2 V in case of error.
Observe the general safety instructions, refer to
ty" on page 8.
The voltage supply for the module logic is generated in the bus coupler and
fed into the S20 module via the bus base module.
For technical data of the supply voltage, refer to
U (logic)" on page 57.
