Beckhoff EL6731-0010 EtherCAT Terminal

The Beckhoff EL6731-0010 is a 1-channel PROFIBUS slave interface terminal that enables seamless data communication between EtherCAT and PROFIBUS networks. It acts as a PROFIBUS DP/DP-V1 slave and can be integrated directly into existing PROFIBUS topologies, allowing EtherCAT-based control systems to interact with PROFIBUS masters at data rates up to 12 Mbaud.

With galvanic isolation, status LEDs, and support for acyclic services and alarms (DP-V1 Class 1 + 2), the EL6731-0010 is ideal for fieldbus bridging in advanced industrial automation systems.
