Application notes
The interface module is equipped with a ribbon cable connector X1 that is used to connect
the output signals of the SIMATIC TDC system, as well as a terminal block X2 for wiring the
plant signals.
The interface module is designed only for vertical mounting positions due to thermal losses
to be dissipated.
Other information
For more information on EMC and environmental conditions, refer to section "General
technical specifications (Page 13)"!
Simultaneous operation of more than three digital outputs in short-circuit mode is not
allowed due to the maximum permissible thermal losses per interface cubicle.
The following figure shows a typical application:
