Beckhoff CU2008 Industrial Ethernet Switch

Description

Industrial networks require robust, highly reliable hardware to ensure uninterrupted communication between controllers and field devices. The Beckhoff CU2008 unmanaged industrial Ethernet switch provides high-speed, 8-port network connectivity designed specifically for demanding control cabinet environments. This compact unit simplifies network topology configuration by enabling direct, noise-resistant connections between multiple Ethernet-enabled devices without the need for complex management software.

Operating as an unmanaged switch with a store-and-forward switching architecture, the CU2008 supports all standard IEEE 802.3-based industrial protocols, including EtherCAT, PROFINET, Modbus TCP, and EtherNet/IP. The integrated auto-negotiation and auto-crossing features facilitate seamless 10/100 MBit/s communication, dynamically adjusting to half- or full-duplex operation depending on the connected network nodes. Its rugged IP20 housing and DIN rail mountable form factor make it an ideal choice for compact infrastructure integration.

Features

• 8 RJ45 ports supporting 10BASE-T and 100BASE-TX physical layers.
• Store-and-forward switching mechanism to prevent corrupted data packets from circulating.
• Auto-negotiation (10/100 MBit/s) and auto-crossing (auto-MDI/MDI-X) features.
• Comprehensive hardware diagnostics via dual LEDs per channel for immediate link, activity, and speed monitoring.
• Compact, space-saving design optimized for DIN rail installation.
• Transparent support for all common IEEE 802.3 Ethernet-based industrial communication protocols.

Applications

• Machine building and production line automation.
• Control cabinet infrastructure expansion.
• Factory automation and process control systems.
• Distributed I/O and industrial PLC network routing.

Connections and Interfaces

Installation Guidelines

• Mounting: Mount the unit vertically onto a standard 35 mm DIN rail (EN 60715) inside a closed control cabinet.
• Grounding: Connect the Protective Earth (PE) terminal to the common ground of the control cabinet to ensure optimal electromagnetic compatibility (EMC) shielding.
• Ventilation: Ensure adequate clearance above and below the switch to allow natural convection cooling, maintaining the ambient temperature within the specified range of 0 to +55 degC.
• Cable Routing: Avoid routing Ethernet cables directly adjacent to high-voltage power lines or variable frequency drive (VFD) output cables to minimize electromagnetic interference.
