BECKHOFF EK1100 Used Working EtherCAT Terminals EtherCAT Coupler

Product Overview

The Beckhoff EK1100 is the cornerstone of any EtherCAT-based control system. This EtherCAT Coupler links the high-speed EtherCAT protocol at the software level to the modular Beckhoff EL/ES-series EtherCAT Terminals at the hardware level. It converts the passing telegrams from Ethernet 100BASE-TX to the internal E-bus signal representation. With its ultra-low latency and high-speed data transmission, the EK1100 is essential for high-performance automation, motion control, and real-time data acquisition. This Used Working unit provides a reliable, industry-proven interface for expanding your distributed I/O network.

Key Features

• High-Speed EtherCAT: Utilizes the full 100 Mbit/s Ethernet bandwidth for near-instantaneous I/O updates.
• Modular Scalability: Supports the connection of up to 65,535 EtherCAT Terminals in a single network segment.
• Dual RJ45 Ports: Features two Ethernet interfaces (In and Out), allowing for easy "line" or "daisy-chain" topology without additional switches.
• E-Bus Conversion: Transparently converts Ethernet signals to the internal Beckhoff E-bus for communication with all attached EL/ES modules.
• Integrated Diagnostics: Front-panel LEDs provide real-time status for "Run," "Link/Activity," and "Error" states for both the network and the E-bus.
• Automatic Addressing: No manual address setting required; the EtherCAT master automatically identifies the coupler's position in the network.
• Industrial Ruggedness: Compact, fanless design with a secure DIN rail mounting clip for reliable operation in harsh environments.

Item Condition (Used - Working)

• Functional Status: Used - Working. This unit has been professionally tested in an EtherCAT environment. It successfully establishes a link with the master and correctly powers/communicates with attached E-bus terminals.
• Physical State: Excellent condition. The gold-plated E-bus side contacts are clean and straight. The RJ45 ports are tight and secure.
• Technical Integrity: No physical damage to the housing or the DIN rail clip. The unit is ready for immediate deployment.
• Visual Reference: Please examine the high-resolution photos to verify the hardware version; the unit pictured is the exact EK1100 you will receive.
