Relay switching outputs OUT1 / OUT2:
The device has two relays with alternate contract that are intended for a voltage of 30 V and
a current of 2 A.

When a higher power is to be switched, the corresponding relays must be
connected externally.
The relays are not bistable and accordingly return to „OFF“ or „RESET“ when all voltage
supplies (battery, USB, external voltage) drop or a system reset is performed.

Observe that the device for the relays has no extra fuse installed. Therefore,
provide an external fuse if required (depending on application case).
Improper wiring and switching of impermissible consumers (buzzer, ignition plus)
may cause a risk of short circuit, fire and loss of the general operating permit.
