Information About EK1814
The EK1814 is part of Beckhoff’s EtherCAT Coupler series, designed to bridge EtherCAT communication with the company’s modular terminal system. Unlike standard couplers, it integrates four digital inputs and four digital outputs directly into the unit, making it ideal for applications with a limited number of I/O points. The device supports the coupling of up to 65,534 EtherCAT Terminals, automatically detecting and assigning each to the process image without manual configuration. It communicates via 100BASE-TX Ethernet using RJ45 connections and supports transmission distances up to 100 meters. Compact, fast, and easy to install, the EK1814 is an efficient solution for distributed control and small-scale automation setups.
Key Features:
- Integrated I/O Functionality: Includes four digital inputs and four digital outputs for direct connection of sensors and actuators.
- High-Speed Data Communication: Operates with 100 Mbit/s EtherCAT data rate for real-time control performance.
- Efficient Signal Conversion: Converts Ethernet telegrams (100BASE-TX) into E-bus representation for terminal communication.
- Wide System Compatibility: Supports connection of up to 65,534 EtherCAT Terminals, enabling large and modular configurations.
- Reliable Electrical Isolation: Provides 500 V separation between Ethernet and E-bus signals for system safety.
- Short-Circuit Protection: Output channels are protected against overload and short-circuit conditions.
- Compact and Durable Design: IP20-rated housing allows easy DIN-rail mounting within control cabinets.
- Automatic Terminal Recognition: Detects connected terminals and updates the process image automatically for simplified setup.
The EK1814 delivers the reliability and precision required for compact automation systems, distributed control networks, and EtherCAT-based machinery integration.
