Beckhoff EL6601 EtherCAT Terminal 1-Port Ethernet Switch Port

Description

Designed to integrate standard Ethernet devices directly into an EtherCAT terminal network, the Beckhoff EL6601 EtherCAT Terminal serves as a highly efficient 1-port Ethernet switch interface. This module enables the decentralized connection of any Ethernet-based devices—such as industrial PCs, vision systems, printers, or third-party controllers—directly to the control network. Operating in store-and-forward switching mode, the terminal supports all standard IEEE 802.3-based Ethernet protocols. Because the Ethernet frames are tunneled through the EtherCAT protocol, it guarantees seamless, transparent communication without disrupting real-time EtherCAT fieldbus performance.

Features

• Single-port RJ45 Ethernet interface supporting 10BASE-T/100BASE-TX.
• Automated configuration via standard EtherCAT E-bus power and communication.
• Built-in IEEE 802.3u auto-negotiation for half- or full-duplex transmission.
• Comprehensive hardware diagnostics via integrated status LEDs.
• Robust electrical isolation of up to 500 V between the E-bus and the Ethernet interface.
• Compact 24 mm housing design for efficient DIN rail utilization.

Applications

• Industrial factory automation and assembly lines.
• Oil and gas control systems requiring hazardous area certifications.
• Integration of external vision systems, barcode readers, and printers.
• Sub-network bridging in wind power and energy generation systems.

Installation Guidelines

• Mount vertically on a standard 35 mm DIN rail conforming to EN 60715.
• Securely lock the terminal in place using the built-in double slot and key connection system for side-by-side modular alignment.
• Ensure a minimum ventilation clearance of 50 mm above and below the module to maintain optimal operating temperatures.
• Utilize shielded twisted-pair (STP) cables up to 100 m in length for reliable communication.
• For hazardous environments, ensure strict compliance with ATEX/IECEx Zone 2 requirements and enclosure ratings.
