Switching variants for monitored alarm and horn outputs with load
resistance monitoring (VdS)
Figure 96: Switching examples for monitored alarm and horn outputs with load resistance monitoring
(VdS)
Rload Load resistance
Rx Additional load resistance
Rcable Line resistance
*
If necessary
* Adaptation of the load resistance.
You will find detailed information regarding the determination of the resistances for
the monitored outputs in the document Planning 008843.
