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:
Power supply: black
EtherCAT: green

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

Connection 1: — Connections for power supply

Pin assignment

Pin	Voltage	Core colors ¹⁾
1	Control voltage U_S	Brown
2	Peripheral voltage U_P	White
3	GND_S	Blue
4	GND_P	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 U_S and U_P 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 U_S and U_P, the maximum permissible current for M8 connectors of 4 A must not be exceeded!
