Connection
Notice | |
Supply voltages can destroy EtherCAT interfaces Connectors for supply voltages have the same design as connectors for EtherCAT. They are not protected against mismating. Avoid mismating. Observe the color coding of the connectors: |
Two M8 connectors at the low-end of the modules are used for feeding and routing the supply voltages:
- IN: left M8 connector for feeding the supply voltages
- OUT: right M8 connector for forwarding the supply voltages
Pin assignment

Pin | Voltage | Core colors 1) |
---|---|---|
1 | Control voltage US | Brown |
2 | Peripheral voltage UP | White |
3 | GNDS | Blue |
4 | GNDP | Black |
1) The core colors apply to Beckhoff ZK2020-xxxx-xxxx cables
Redirection of the supply voltages
The IN and OUT power connections are bridged in the module (not IP204x-Bxxx and IE204x). The supply voltages US and UP can thus easily be transferred from EtherCAT Box to EtherCAT Box.
Notice | |
Pay attention to the maximum permissible current! Pay attention also for the redirection of the supply voltages US and UP, the maximum permissible current for M8 connectors of 4 A must not be exceeded! |
