6.4 Bus cover Power over EtherCAT (PoE)
Based on the IEEE-standard 802.3af, the Baumer EtherCAT encoder with PoE bus cover is interacting as PD
(Powered Device) with a corresponding PSE (Power Sourcing Equipment) module. Signal and power
transmission is by 4-wire standard EtherCAT/Ethernet cable (for example CAT-5). The PSE will identify the
encoder as PD after power on by the procedure specified in IEEE standard 802.3af.
Encoder supply of 48 V must be provided by an auxiliary PSE module (for example Beckhoff EtherCAT
branch EK1132).
