Internal schem- On the V+/GND pin, it is possible to feed in a voltage of around 12.5 - 24 V (+ max. 20%)
atic connection with an external power supply. The outputs IO 0 - 5 can then be operated with the
diagram of the external voltage. A maximum of 1 A can be drawn per output, with a maximum of 3 A
IOs allowed in total. The fuse protection must be located externally.
