The EK1501-0010 has two SC duplex sockets and three hexadecimal ID switches.

The coupler is connected to the network via the upper Ethernet connection. 

The lower SC duplex socket may be used to connect further EtherCAT devices in

the same segment. The single-mode fiber-optic connection facilitates distances

between two couplers of up to 20 km. A group of EtherCAT components can be

assigned a unique ID via the hexadecimal ID switches. This group can then be

located at any position within the EtherCAT network. Variable topologies are

therefore easily implementable. In addition, an EtherCAT junction or an EtherCAT

extension can be used for the extension or for setting up a line or star topology.

The system and field supply, each 24 V DC, is provided directly at the coupler.

The attached EtherCAT Terminals are supplied with the current required for

communication from the supplied system voltage. The coupler can supply a

maximum of 5 V and 2 A.

Power feed terminals (e.g. EL9410) must be integrated if more current is required.

The field supply is forwarded to the individual I/O components via the power

contacts with up to 10 A.
