Feed-in
Two M8 connectors at the bottom of the EtherCAT P Box are used for feeding and routing the supply voltages.
- IN (X60): left M8 connector for feeding the supply voltages
- OUT (X61): right M8 connector for routing the supply voltages
Pin assignment
Contact | Voltage | |
|---|---|---|
1 | Control voltage Us, +24 VDC | |
2 | Peripheral voltage Up, +24 VDC | |
3 | GNDs |
|
4 | GNDp | |
The contacts of the M8 connectors can conduct a maximum current of 4 A.
Control voltage US
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the control voltage US. The control voltage is electrically isolated from the fieldbus circuitry.
Peripheral voltage UP
The peripheral voltage UP supplies the digital outputs; it can be brought in separately. Hence, if the peripheral 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 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.
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!
