Contact Multiplier
The application of the SICAM I/O Unit as contact multiplier according to Figure 5-5 is for example used for the
multiplication of signals on one or several binary inputs (BI1 to BI3) for additional contacts. In the case of longer
supply lines, the pickup value of the threshold value voltage can be parameterized to increase the signal-to-
noise ratio for binary inputs (dependent on the adjusted binary input voltage).
Input signals on terminal block N can be either parameterized on relay outputs on terminal block N or on ter-
minal block P. The same is the case for inputs signals on terminal block P.

Contact Multiplier
1 Binary Signal on up to 6 Relay Outputs
The binary signal gets to the relay module via the selected binary input of the SICAM I/O Unit. Depending on
parameterization, the relay contacts are controlled simultaneously and parallel by up to 6 relay outputs. This
allows, for example, an indication to be output to up to 6 different users simultaneously.
Several Binary Signals on Relay Outputs
Several binary signals get to the relay module via the selected binary inputs of the SICAM I/O Unit. Depending
on parameterization, they are assigned simultaneously and parallel to the parameterized relay outputs.
