I/O System Reduces Complex Wiring


Combining ultra-fast EtherCAT communication and power supply in a standard 4-wire Ethernet cable, the EtherCAT P solution eliminates the need for separate power lines for connected sensors, actuators, and EtherCAT P slaves. This makes EtherCAT P the ideal sensor, actuator and measurement bus, providing advantages both for connecting small remote I/O stations in terminal boxes and for decentralized I/O components located throughout the process.


A full range of EtherCAT P system and I/O components in protection class IP 67 and 4-wire Ethernet cables is currently available for the 24 V I/O level. The power supply from EtherCAT P is rated at 2x 24 V DC/3A. For connecting sensors and actuators with power supply, users can integrate any of the wide range of well-established EP Box modules from Beckhoff in the new EPP versions for EtherCAT P.



The following IP 67 infrastructure components are available to set up the required network architecture in the field:

  • EPP1111 EtherCAT P Box with ID switch
  • EPP1322 EtherCAT P junction with power feed-in and junctions with or without power refresh (EPP1332/EPP1342)
  • EPP9001 EtherCAT P/EtherCAT connector with power transmission
  • EPP9022 EtherCAT P Box for diagnosing Us (system and sensor supply) and Up (peripheral voltage for actuators)
