Beckhoff EK1501-0010 EtherCAT Coupler Module

The Beckhoff EK1501-0010 EtherCAT Coupler Module with ID switch is the fieldbus-to-Terminal interface that links the EtherCAT protocol at the fieldbus level to Beckhoff EtherCAT Terminals, with a fiber-optic data path for EMI immunity and electrical isolation. It provides a dual single-mode fiber optic interface with 2 x SC duplex ports (SM fiber) for long-distance communication, typically operating at a transceiver wavelength of 1310 nm under Laser Class 1 safety, and supports an EtherCAT device protocol at 100 Mbaud. This coupler supports HotConnect with address setting on the device and accommodates up to 4096 configurable IDs, making it suitable for large-scale EtherCAT I/O networks. The EK1501-0010 is designed to bridge distances between stations—up to 20 km in appropriate 100BASE-FX configurations—while maintaining precise real-time EtherCAT timing. Ideal for factory automation installations requiring fiber-optic links between a master and remote EL-series terminals, it offers the reliability of fiber in environments with high electrical noise or where extended reach is essential.
