EK1561

EK1561 is a Beckhoff coupler in the EK EtherCAT Couplers series. It supports EtherCAT distributed clocks, which synchronize timing across compatible network devices. A CoE interface is not included, so CANopen over EtherCAT communication is unavailable.

The coupler operates from a 24 VDC supply using SELV or PELV protective extra-low-voltage power. Its E-bus supply provides up to 2 A for connected EtherCAT terminals. The unit has three potential groups, allowing connected circuits to be separated into distinct electrical sections.

Three power contacts distribute field power through the terminal assembly. These contacts operate at 24 V and support a current of up to 10 A, providing power connections for compatible downstream terminals and field devices.
