Circuit diagram
The digital outputs are high switches or P switches between the applied load voltage L+
and the 4 digital outputs [0..3] with common root.

Protective function
The output channels provide a self-protection function in order to avoid damages to the
device under fault conditions in the load circuit as far as possible. Each load current of
all 4 channels per channel root is monitored. The protected range begins when the value
is higher than approx. 0.6 A per channel. It may happen, that the channel is already
switched-off at this value, i. e. all output signals of this root are set to logical 0.
In this case, status signals report the error status to the iba applications. The errors can
be reset by the application, but only when the error does not physically exist any longer.
