Product Description:

The EL6731-0000 is a Beckhoff terminal that acts as a PROFINET RT interface, enabling communication between EtherCAT and PROFINET networks. This terminal facilitates seamless data exchange and integration between different automation systems, making it ideal for applications that require communication between EtherCAT and PROFINET devices. The terminal supports varying DP cycle times for each device through its CDL. It features one Fieldbus channel, making it straightforward to connect to the PROFIBUS network. The terminal offers data transfer rates from 9.6 kbaud up to 12 Mbaud, providing flexibility to accommodate various application needs.

This terminal is equipped with one D-sub 9-pin socket interface, which provides a reliable and secure connection to the PROFIBUS network. This interface is galvanically decoupled, ensuring that the terminal and connected devices are protected against electrical interference. The terminal consumes 200 mA from the E-bus, making it relatively efficient for integration into automation systems. It supports distributed clocks, allowing users to synchronize communication between connected devices. The terminal has a maximum bit width of 1.4 kbytes for both input and output data, supporting the transfer of large amounts of data.

The EL6731-0000 offers robust resistance to mechanical stress providing vibration and shock resistance in line with EN 60068-2-6 and EN 60068-2-27 standards. This ensures that the terminal can withstand adverse operating conditions without losing reliability. It is also suited for conditions where there may be fluctuations in temperature, accommodating a -25 to +60°C operating range. This unit is susceptible to moisture damage since it features an ingress protection level of IP 20 which only safeguards against solid objects. The unit weighs 70 g and measures 24 mm x 100 mm x 52 mm, providing a compact build that integrates seamlessly into existing setups.
