Beckhoff EK1501 | EtherCAT Coupler with ID switch, multi-mode fiber optic

The EK1501 EtherCAT Coupler with multi-mode fiber-optic connection is the

link between the EtherCAT protocol at fieldbus level and the EtherCAT

Terminals. The coupler converts the passing telegrams from Ethernet

100BASE-FX to E-bus signal representation.

A station consists of a coupler and any number of EtherCAT Terminals

that are automatically detected and individually displayed in the process

image.

Special features:

• connection technology 2 x multi-mode fiber-optic connection via SC duplex

• connection lengths up to 2 km

• 3 ID switches for implementing variable topologies

• number of EtherCAT Terminals in the overall system: up to 65.535

The EK1501 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 multimode glass fiber connection enables distances

of up to 2 km between two couplers. 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.
