Product Description:
The EK1101-0010 is an EtherCAT coupler manufactured by Beckhoff within the EK EtherCAT Couplers series. Acting as the first node of an I/O station, it converts fieldbus frames from an upstream master into the internal terminal interface so that digital and analog modules can be read or written in real time. The housing clips onto a 35 mm DIN mounting rail, allowing quick cabinet installation while keeping depth minimal for shallow enclosures. This product links decentralized sensors and actuators to a controller without separate gateways, reducing wiring and cycle-time overhead in industrial automation.
Communication operates at a 100 MBaud line rate using the EtherCAT Device Protocol over Ethernet 100BASE-TX cabling. Two RJ45 ports form the in-line bus connection, so segments can be daisy-chained without external switches. Typical frame propagation through the coupler adds only 1 µs of delay, which keeps synchronous tasks aligned across axes. The module accepts a 24 VDC supply that powers its logic and forwards the field voltage to the power contacts. An IP20 protection rating makes it suitable for installation in protected control cabinets. The network supports up to 4,096 hot-connect IDs for live reconfiguration, and the extended copper link length can reach 300 m when repeaters or media converters are used.
The process image that the EK1101-0010 presents to the controller can grow to 4.2 GB, providing capacity for complex machines with extensive process data. A station may include as many as 65,535 EtherCAT terminals under one address map. The internal power feed supports a maximum of 10 A on the power contacts, allowing sensors or actuators to receive power through the terminal chain. Copper segments can extend up to 100 m between nodes while maintaining reliable communication and suitable bus timing. Large I/O arrangements can therefore operate within one address map without requiring separate subnetworks.
