Supplying the inputs of the basic unit
There are three possibilities for supplying the inputs:
• a): 24 V DC internal
• b): 24 V DC external However, input 3 is the reference potential, i.e.
three inputs are available.
• c): 24 V DC external Only possible for basic units with a supply voltage of
24 V DC!
Fig. 13-9: 24 V DC for supplying the inputs
All inputs work reactionless, i.e. the signal statuses on neighboring inputs
do not influence each other.
