BECKHOFF EL6752 EtherCAT Terminal DeviceNet Master Module

Description

Integration of legacy DeviceNet fieldbus topologies into high-speed EtherCAT networks is achieved directly through the EL6752 communication module. This 1-channel terminal operates as a fully functional DeviceNet master (scanner), allowing the connection of up to 63 decentralized DeviceNet slaves to a centralized EtherCAT control loop. The module acts as an efficient bridge, handling local fieldbus diagnostics and signal mapping with high deterministic accuracy.

The BECKHOFF EL6752 features physical and galvanic isolation to protect internal E-bus circuitry from external electrical transients. Its compact 24 mm housing integrates status LEDs for rapid visual diagnostics of bus communication status, network errors, and power supply. This interface is optimal for retrofitting existing manufacturing lines, integrating legacy sensors, and managing distributed I/O systems in heavy industrial environments.

Installation Guidelines

• Mounting: Mount horizontally or vertically on a standard 35 mm DIN rail conforming to EN 60715. Use the integrated locking mechanism for secure placement.
• Wiring: Use specialized push-in connections for E-bus communication and the provided 5-pin open style connector for DeviceNet cabling.
• Shielding & Grounding: Ensure the DeviceNet cable shield is properly terminated at the connector to minimize electromagnetic interference (EMI).
• Environmental: Maintain operating ambient temperature within -25 degC to +60 degC. Ensure the installation cabinet provides adequate ventilation to achieve an IP20 rating.
