Information About EK1818
The EK1818 is part of Beckhoff’s EtherCAT I/O system, serving as the interface between an EtherCAT network and connected EL-series terminals. It supports high-speed EtherCAT communication with minimal latency and allows expansion to a large number of terminals. The coupler integrates eight digital inputs and four digital outputs, reducing the need for additional I/O modules. Its high-density housing and DIN rail mounting make it suitable for space-efficient control cabinet installations.
Key Features:
- Integrated Digital I/O: Includes 8 digital inputs and 4 digital outputs for direct signal processing.
- EtherCAT Network Interface: Connects EtherCAT Terminals to 100BASE-TX EtherCAT networks.
- High-Speed Data Transfer: Supports 100 Mbit/s communication with approximately 1 µs delay.
- Expandable Terminal Support: Enables connection of up to 65,534 EtherCAT Terminals.
- Robust Electrical Isolation: Provides 500 V isolation between power, E-bus, and Ethernet interfaces.
- DIN Rail Mounting: Designed for installation on standard 35 mm DIN rails.
- Industrial Compliance: Meets EN, CE, and UL standards for industrial automation.
The EK1818 delivers the reliability and precision required for integrated EtherCAT I/O coupling and real-time industrial communication.
