Intelligent Distributor

The intelligent distributor of the SIM performs the following tasks:

• Power supply for each individual satellite.
• Current limitation for each individual satellite.
• Power shutdown for each individual satellite in the event of a fault.

In order to ensure reliable function of the ISIS, all the satellites are supplied with voltage centrally by the SIM. To ensure that the system functions perfectly in the event of a short circuit or overload on one of the supply lines, there must be an intelligent current distribution.

The distributor integrated in the SIM limits the current on each supply line to the satellites to 100 mA (Approx. 10V). An exception is the SZL, which has a current intake of approx. 120 mA, as the steering wheel electronics are also supplied.

If this current limit is exceeded, it causes a reduction in the current output. It is also possible to switch off each individual satellite.
