Beckhoff: Ethernet protocol and peripheral voltage in one cable

With the newly introduced EtherCAT P technology, Beckhoff unites EtherCAT communication and power functions in a standard, 4-wire Ethernet cable: One Cable Automation technology integrates the 24 V DC supply of the EtherCAT P slaves with the signals and data from connected sensors and actuators.

In addition, the system electrically isolates the US (system and sensor supply) and UP (peripheral voltage for actuators) from each other, each with up to 3A of current for the connected components. All the benefits of EtherCAT are included in EtherCAT P, such as: free choice of networktopology, high speed communication, optimum bandwidth utilization, telegram processing on-the-fly, highly precise synchronization and extensive diagnostics functionality. The US and UP currents are directly injected into the wires of the 100Mbit/s cable, resulting in a cost-effective and compact connection.
