Information About EK1101
The EK1101 is part of the Beckhoff EtherCAT I/O system, developed to provide modular and high-performance distributed I/O solutions. It features two RJ45 EtherCAT ports—one for upstream connection to the EtherCAT master and one for downstream continuation to other EtherCAT devices. The coupler transfers both data and 24V DC power for the internal electronics of connected EL terminals. It supports 100 Mbit/s full-duplex real-time communication and can connect up to 65,535 EtherCAT terminals in a single segment. Integrated status LEDs indicate power, link, and activity states, simplifying commissioning and diagnostics. Its compact, DIN rail–mounted design allows easy integration into control panels and scalable expansion of EtherCAT networks.
Key Features:
- Design: EtherCAT coupler for modular I/O systems.
- Connectivity: Two RJ45 EtherCAT ports (upstream and downstream).
- Performance: 100 Mbit/s full-duplex communication for real-time control.
- Capacity: Supports up to 65,535 EtherCAT EL terminals.
- Power Supply: Provides 24V DC to internal electronics of connected terminals.
- Diagnostics: LED indicators for power, link, and activity status.
- Installation: Compact DIN rail–mounted design for distributed architectures.
- Application Range: Suitable for machine automation, robotics, and process control.
The EK1101 delivers the speed, modularity, and reliability required for building scalable EtherCAT-based distributed I/O systems.
