In one standard 4-wire Ethernet cable, EtherCAT P integrates 24 Vdc supply of EtherCAT P slaves with signals and data from connected sensors/actuators. US (system and sensor supply) and UP (peripheral voltage for actuators) are electrically isolated from each other, each with up to 3 A current for connected components. US and UP currents are directly injected into wires of 100 Mbps cable, and EtherCAT P covers applications from 24 V I/O level through drives with 400 or 600 Vdc.
