PE Earthing connection
The contacts of the M8 plug connectors can conduct a maximum current of 4 A.
Two LEDs indicate the status of the supply voltages.
Do not confuse the power port with EtherCAT port!
Never connect the power cables (M8, 24 V
Modules. This can cause the destruction of the modules!
Control voltage Us: 24 V
Power is supplied to the fieldbus, the processor logic and also to the inputs from the 24 V
Us. The control voltage is electrically isolated from the fieldbus circuitry.
Peripheral voltage Up: 24 V
The peripheral voltage Up supplies the digital pulse outputs; it can be brought in separately. Hence, if the
load voltage is switched off, the fieldbus function as well as the supply and function of the inputs are
retained.
Redirection of the supply voltages
The power IN and OUT connections are bridged in the module. Hence, the supply voltages Us and Up can
be passed from EtherCAT Box to EtherCAT Box in a simple manner.
