Fig. 5-12: Digital outputs
Note: The digital outputs have been realized with so-called high-side
switches. This means that these outputs can actively supply
current but not drain it.
Note: The energy absorption capacity of the outputs is used to limit
voltage peaks caused when inductive loads are switched off.
Limit voltage peaks by using free-wheeling diodes directly at
the relay coil.
