Description

Engineered to bridge fieldbus technologies, the Beckhoff EL6751 serves as a high-performance 1-channel CANopen master/slave interface within an EtherCAT Terminal system. This communication terminal enables the seamless integration of CANopen-compliant fieldbus devices directly into the high-speed EtherCAT network. It can act as a CANopen network master and manager, or optionally operate as a CANopen slave, providing flexible architecture options for decentralized industrial networks.

The EL6751 offers robust galvanic decoupling and a standard 9-pin D-sub interface to ensure clean, noise-immune signal transmission in harsh industrial environments. By supporting both standard CANopen communication profiles and RAW-CAN protocol options, this terminal accommodates a wide range of legacy and modern automation devices.

Features

Single-channel communication interface supporting CANopen master, CANopen manager, or optional CANopen slave operation.
Galvanically decoupled D-sub interface (9-pin) conforming to standard CANopen specifications.
Flexible data transfer rates ranging from 10 kbaud up to 1,000 kbaud (1 Mbaud).
Comprehensive hardware diagnostics via integrated status LEDs.
Supports RAW-CAN protocol for customized CAN bus communication requirements.
Compact 24 mm terminal housing with integrated slot-and-key side-by-side mounting.

Applications

Industrial manufacturing plants utilizing distributed fieldbus architectures.
Integration of legacy CANopen-compliant sensors, actuators, and drives into EtherCAT networks.
Heavy machinery and specialized control systems requiring CANopen master/slave configuration.
Process automation and water treatment plants utilizing hybrid fieldbus solutions.
