The Beckhoff CU2508 is a high-performance Ethernet port multiplier designed to facilitate the connection of eight independent Ethernet networks. This device is connected to the PC via a gigabit uplink, enabling efficient data transfer to the multiplier. The CU2508 then allocates the data to the relevant 100BASE-TX port based on an analysis of a frame prefix and dispatches them with microsecond precision.
This port multiplier is ideal for applications that require multiple Ethernet ports to be realised outside the PC. It is supported by TwinCAT, eliminating the need for additional network ports on the PC. For demanding applications, an EtherCAT installation can be distributed or expanded to up to eight lines with the CU2508, significantly enhancing performance.
The CU2508 is also capable of synchronising the distributed clocks of the EtherCAT lines. Furthermore, it can realise an EtherCAT cable redundancy with simultaneous usage of distributed clocks using two ports.
With its support for Ethernet TCP/IP and real-time protocols such as EtherCAT, PROFINET, EtherNet/IP, and others, the Beckhoff CU2508 offers versatility and high performance in a compact package. It features eight 100 Mbit/s Ethernet ports and one 1 Gbit/s uplink, an RJ45 Ethernet interface, and supports cable lengths of up to 100m twisted pair.
The CU2508 also includes LED indicators for hardware diagnosis and operates on a 24V power supply. This robust and reliable device is an excellent choice for enhancing network connectivity and performance in a variety of industrial applications.
