The Beckhoff EL2808 EtherCAT Terminal is a compact and robust digital output module designed to deliver reliable 24 V DC switching for decentralised automation systems. With eight output channels integrated into a single EtherCAT Terminal, the EL2808 provides a high channel density solution for controlling actuators, signal lamps, and other field devices directly from the control system.

Each output channel supports a nominal voltage of 24 V DC (-15%/+20%) with a maximum output current of 0.5 A per channel. This ensures reliable operation across a wide range of loads, including ohmic, inductive, and lamp types. The design makes the EL2808 versatile enough for tasks such as switching solenoid valves, relay coils, indicator lights, or other DC-driven devices commonly used in machine and process automation.

For durability and safety, the outputs are short-circuit proof and incorporate reverse voltage protection. In the event of a wiring error or overload, the terminal is safeguarded from damage, ensuring both system resilience and reduced downtime. The typical short-circuit current of less than 2 A helps protect downstream devices while maintaining stable operation across all channels.

The EL2808 uses 2-wire connection technology, simplifying installation and wiring efforts. This compact wiring method not only reduces setup time but also helps achieve clean and organised cabinet layouts. Its modular format allows seamless integration with other EtherCAT Terminals, enabling highly customised and scalable automation systems.

As part of the EtherCAT I/O system, the EL2808 benefits from EtherCAT’s high-speed, deterministic communication. Output commands are transmitted with minimal latency, making the terminal suitable for time-critical automation tasks. Synchronisation across multiple terminals ensures that outputs operate reliably and in step with system-wide processes, enhancing coordination in distributed control environments.

With its compact design, the EL2808 conserves valuable cabinet space while delivering high channel density. This efficiency makes it an excellent choice for applications where multiple outputs must be controlled from a small footprint, such as packaging machinery, material handling systems, or building automation installations.

In practice, the EL2808 is widely used in applications requiring direct switching of actuators and indicators in decentralised machine control. Its robustness, flexibility, and seamless EtherCAT integration make it a dependable component for both standard and advanced automation projects.

In summary, the Beckhoff EL2808 EtherCAT Terminal offers a high-performance, space-saving solution for digital output control. With eight channels, 24 V DC compatibility, short-circuit proof design, and versatile load support, it provides engineers with a reliable and efficient module for modern automation systems.
