Electrical installation
4.10 Other connections
The maximum cable length that can be connected is 10 m.
Note
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
This power supply is required for the digital outputs only.
The electronics power supply and the power supply for the analog inputs/outputs are taken
from the option slot of the Control Unit.
Note
The power supply of the digital outputs and the electronic power supply of the Control Unit
are isolated.
Note
If the 24 V supply is briefly interrupted, then the digital outputs are deactivated during this
time.
