The EK1814 is a high-performance EtherCAT Coupler designed to link the EtherCAT protocol with up to 65,534 EtherCAT Terminals (ELxxxx). Manufactured by BECKHOFF, this device functions as the interface between the EtherCAT fieldbus and the individual terminal blocks. Beyond its coupling function, the EK1814 features 4 integrated digital inputs and 4 integrated digital outputs, providing a space-efficient solution for decentralized control systems. It utilizes 100BASE-TX communication at 100 Mbit/s and includes comprehensive diagnostic LEDs to monitor terminal and bus status.

Features

  • Coupling of EtherCAT Terminals to 100BASE-TX EtherCAT networks
  • Integrated I/O: 4 digital inputs and 4 digital outputs (0.5 A per channel)
  • High capacity: Supports up to 65,534 EtherCAT Terminals
  • Short-circuit-proof outputs with reverse voltage protection
  • Rapid data transfer rate of 100 Mbit/s with ~1 µs delay
  • Compact High Density (HD) housing with plug-in wiring technology
  • Electrical isolation of 500 V between bus and field potentials

Applications

  • Distributed I/O systems for machine and plant automation
  • High-speed industrial communication gateways
  • Space-constrained control cabinets requiring integrated I/O functionality
  • Modular manufacturing lines using EtherCAT technology

Installation Guidelines

  • Mount the unit on a 35 mm DIN rail (EN 60715) and engage the locking mechanism for a secure fit.
  • Ensure the use of shielded Cat.5 (or better) Ethernet cabling for the 100BASE-TX interface to prevent EMI.
  • Use the direct plug-in technique for solid conductors, or a screwdriver for spring-actuation with stranded wires.
  • Maintain the total power contact load (Imax) below 10 A.
  • Operating in an IP20-rated environment is required; ensure the installation location provides adequate protection against contaminants and moisture.
