Beckhoff EL6731 Digital Input Module Master Module Industrial Bus Coupler

Beckhoff EL6731 is a standard EtherCAT terminal master module industrial bus coupler designed for industrial automation control systems

This module acts as a bridge between EtherCAT main control system and PROFIBUS slave field devices

It converts real time EtherCAT bus data into standard PROFIBUS communication signals to realize two way data transmission

Users can connect PROFIBUS sensors frequency converters remote IO stations and other field equipment through this module

The module transmits digital input digital output and analog signal data between upper EtherCAT controller and PROFIBUS field terminals

It realizes unified equipment logic control and data collection on mixed bus production lines to solve signal interconnection problems of different industrial communication protocols

1. Integrated PROFIBUS master function

   Works as independent PROFIBUS master station without extra gateway equipment reduces cabinet wiring quantity and overall equipment cost

2. Standard EtherCAT terminal stacked structure

   12 millimeter narrow housing supports stacked installation on DIN rail together with other BeckCAT IO terminals flexible layout inside control cabinet

3. Bidirectional high speed data transmission

   Supports real time exchange of process data between EtherCAT and PROFIBUS stable signal transmission without obvious delay during multi device linkage operation
