4.8.3 Examples for voltage supply
Figure 4-19 Example for the supply and forwarding of supply voltages
4.8.4 Supply line and power supply (M12)
For M12 connectors in Axioline E devices, a maximum of 12 A per contact is permitted.
To ensure that this condition is met, the following factors must be considered:
1. Current consumption of the Axioline E devices (see data sheets)
2. Current consumption of the connected sensors
3. Current consumption of the connected actuators
4. Length of the cables and losses on these cables
NOTE: Damage to the electronics
The total current at U
S
must not exceed 12 A.
The total current at U
A
must not exceed 12 A.
It is particularly important that these factors are observed when forwarding the supply
voltage.
