Inputs and outputs
NOTE:SubjectterminalblockX0
The terminal Uext serves to feed the outputs to terminals 7 ... 10th
If at least I / O 4 ... 7 operated as a receipt, the following must be considered:
IfthisexternalsupplyUextwhichoutputsthepowero󰀨andtheinputsI/O4...
7 is still tension on the supply voltage of the outputs O 0, ... 3 and I / O 4 ... 7 via
the built-in output transistor of the I / Os diode fed back and would feed the device
connected to the output load.
