Product Description:

Beckhoff EtherCAT terminal EL6731-1009 is a high-performance part that solves the compatibility between EtherCAT and PROFIBUS DP networks, being a cost-effective and efficient option for the industry. This terminal is a part of Beckhoff’s EL EtherCAT Terminal Series and enables easy interoperability between EtherCAT systems and PROFIBUS DP devices. It implements both the PROFIBUS DP and DP-V2 protocols so as to interface with different devices and applications. There is a 9 pin D sub socket on the terminal to connect the terminal to the PROFIBUS network and different baud rates from 9.6 kbaud and 12Mbaud are supported to accommodate different industrial requirements. Designed to handle up to 125 slaves, the EL6731-1009 is perfect for use in complex Big Systems connecting multiple devices into one network. This scalability is especially important in manufacturing and process industries where many PROFIBUS devices are required to operate quickly.

Also, the terminal has distributed clocks to maintain synchronization across the network and improve the real-time communication and control. For quick identification of the terminal’s performance, there are status LEDs for hardware to provide details about the hardware’s status. This one measures 70 grams and is 75mm x 45mm in size, making this model suitable for applications where space is at a premium and the device is likely to be installed into a control cabinet, for instance.

The EL6731-1009 is equipped with safety and quality recognitions of CE, UL, ATEX, and IECEx, to ensure the product is protected with high safety and reliability. In summary, this terminal is a strong and compact solution for the integration of PROFIBUS in EtherCAT systems with universal communication performance for today’s industrial applications.
