Mounting and cabling
Auxiliary voltage Up 24 V
DC
The Auxiliary voltage Up supplies the digital outputs; it can be brought in separately. If the load voltage is
switched off, the fieldbus functions and the power supply and functionality of the inputs are retained.
Redirection of the supply voltages
The IN and OUT power connections are bridged in the module (not IP204xBxxx and IE204x). The supply
voltages Us and Up can thus easily be transferred from EtherCAT Box to EtherCAT Box.
Attention
Pay attention to the maximum permissible current!
Pay attention also for the redirection of the supply voltages Us and Up, the maximum per
missible current for M8 connectors of 4 A must not be exceeded!
Supply via EP92x40023 PowerBox modules
If the machine requires higher current or if the EtherCAT Box Modules are installed far away from the control
cabinet with included power supply, the usage of four cannel power distribution modules EP9214 or EP9224
(with integrated data logging, see
With these modules intelligent power distribution concepts with up to 2 x 16 A and a maximum of 2.5 mm²
cable crosssection can be realized.
