Power Connection
The feeding and forwarding of supply voltages is done via two M8 connectors at the bottom end of the
modules:
• IN: left M8 connector for feeding the supply voltages
• OUT: right M8 connector for forwarding the supply voltages

The pins M8 connectors carry a maximum current of 4 A.
Two LEDs display the status of the supply voltages.
NOTE
Don't confuse the power connectors with the EtherCAT connectors!
Never connect the power cables (M8, 24 V
DC
) with the green marked EtherCAT sockets of the EtherCAT
Box Modules! This can damage the modules!
Control voltage Us: 24 V
DC
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the 24 V
DC
control
voltage Us. The control voltage is electrically isolated from the fieldbus circuitry.
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.
