Product Description:

The EL6731-1006 terminal features a compact design with dimensions of 24 mm x 100 mm x 52 mm. It is a Beckhoff module that is designed to support the full range of PROFIBUS protocol features, communicating effectively with devices on a PROFIBUS network such as sensors and actuators. It enables data exchange, diagnostic functions, and real-time control between EtherCAT and PROFIBUS devices, ensuring smooth operation across both networks in automation setups. The terminal features a high-precision isochronous mode, ensuring precise timing and smooth coordination in axis control. It also offers expanded diagnostic options to provide detailed feedback about the status of connected devices, making it easier to troubleshoot system faults.

The EL6731-1006 includes a 9-pin D-sub socket as its interface. This interface provides a stable connection between the PROFIBUS network and the EtherCAT terminal, allowing seamless communication. The design of the D-sub socket ensures secure physical connections, which are essential for maintaining signal integrity. The terminal supports distributed clocks which ensure that all connected devices operate in harmony for accurate timing and coordinated control. Its data transfer rates range 9.6 kbaud to 12 Mbaud, depending on application requirements. This allows for flexible communication speeds to match a wide range of automation system demands.

This terminal can support up to 125 PROFIBUS slaves, with each slave capable of handling up to 244 bytes. It allows for a maximum of 1.4 kilobytes of input data and 1.4 kilobytes of output data, enabling comprehensive data exchange. The terminal draws 200 mA from the Ebus, operating efficiently within the control system. Its robust build is suited for standard industrial conditions, operating effectively at -25°C to +60°C. It also meets electromagnetic compatibility (EMC) standards outlined in EN 61000-6-2 and EN 61000-6-4.
