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.

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.

Compliance and Certifications

  • CE
  • UL

FAQ

Is the Beckhoff CU2008 switch compatible with EtherCAT networks?

Yes. The Beckhoff CU2008 unmanaged switch supports all Ethernet (IEEE 802.3)-based industrial protocols, making it suitable for distributing EtherCAT, PROFINET, Modbus TCP, and standard TCP/IP traffic.

What is the maximum recommended cable length for the CU2008?

The CU2008 supports a maximum transmission distance of up to 100 meters using standard twisted-pair copper Ethernet cables.

Does the CU2008 switch require software configuration?

No, the CU2008 is an unmanaged switch. It features automatic auto-negotiation and auto-crossing (MDI/MDI-X), meaning it operates immediately upon being wired and powered on without requiring configuration software.
