EL6731-1009
by Beckhoff
The Beckhoff EL6731-1009 EtherCAT terminal is part of the EL EtherCAT Terminals series by Beckhoff. It supports the PROFIBUS DP fieldbus protocol and features a 9-pin D-sub interface for straightforward connection. With a data transfer rate ranging from 9.6 kbaud to 12 Mbaud and the ability to connect up to 125 slaves, its primary function is to bridge EtherCAT and PROFIBUS DP networks, ensuring reliable, high-speed industrial communication.
Technical specifications mirror high-performance design: the terminal handles a single fieldbus channel compatible with PROFIBUS DP/DP-V1/DP-V2/MC protocols and provides a process image size of 1.4 kbyte input and 1.4 kbyte output. It draws a typical 200 mA E-bus current and operates within an ambient temperature range of -25…+60 °C, with storage tolerance of -40…+85 °C. The 1×9-pin D-sub connector is galvanically decoupled for enhanced signal integrity, while distributed clocks ensure precise synchronization across the network. For immediate status feedback and fault detection, hardware diagnostics are provided via status LEDs.
Additional features include a compact footprint weighing approximately 70 g, making it ideal for densely populated control cabinets and space-constrained environments. The capability to handle up to 244 bytes per slave and integrated distributed clocks support large-scale, time-critical applications. Conformity with rigorous environmental and performance criteria ensures durability and efficient operation in harsh industrial settings. Overall, the EL6731-1009 delivers seamless integration of PROFIBUS DP devices into EtherCAT networks, greatly enhancing scalability, synchronization, and reliability for modern automation systems.
