Beckhoff EL6751 Digital Input Module with CANopen Communication Interface Slaves

Beckhoff EL6751 is a standard EtherCAT terminal designed for industrial automation control systems equipped with independent CANopen communication interface.

This module serves as protocol conversion gateway between EtherCAT master control system and all kinds of CANopen slave field devices.

It completes bidirectional conversion of EtherCAT bus data and CANopen bus data to realize real time signal interaction.

Users can connect CANopen servo drives remote IO modules sensors hydraulic proportional valves and encoders through this terminal.

The module collects digital input signals digital output signals and analog process data from CANopen slave equipment and uploads all data to upper EtherCAT controllers.

It solves communication matching problems of mixed bus automation equipment and supports unified logic motion and process control on production lines with dual bus architecture.
