The Beckhoff EL1008 is a compact EtherCAT digital input terminal with 8 channels for 24 V DC signal acquisition. Designed for efficiency and reliability, it provides decentralised signal collection in automation systems while maintaining the high-speed, deterministic communication EtherCAT is known for.

Each of the eight inputs is designed according to EN 61131-2 type 1/3 standards, ensuring full compatibility with a wide range of industrial sensors, switches, and pushbuttons. With a typical input current of 3 mA (type 3), the terminal guarantees stable recognition of connected devices without overloading sensor circuits.

To ensure signal stability, the EL1008 integrates a 3.0 ms input filter on every channel. This filter reduces the effects of noise and signal bouncing, enabling accurate detection even in electrically noisy industrial environments. The result is reliable performance in applications where precise and consistent signal acquisition is critical, such as packaging machinery, robotics, and process control.

Operating at a nominal input voltage of 24 V DC (-15%/+20%), the EL1008 aligns with widely adopted industry standards. Its 1-wire connection technology simplifies wiring, reducing setup effort and space requirements in control cabinets. With its compact EtherCAT form factor, the module allows engineers to scale input capacity easily without expanding cabinet size excessively.

Power efficiency is another advantage of the EL1008. It consumes just ~90 mA from the EtherCAT E-bus and a minimal 2 mA plus load from power contacts, making it highly suitable for installations with large numbers of terminals. This low consumption supports dense I/O configurations without placing excessive demands on system power.

Like all Beckhoff EL terminals, the EL1008 integrates seamlessly into the EtherCAT ecosystem, allowing for straightforward configuration and diagnostics through TwinCAT software. This modular approach ensures flexibility in system design—users can mix and match input, output, and specialty terminals to suit their exact application needs.

In practical use, the EL1008 is widely deployed in machine building, building automation, materials handling, and production systems. It enables efficient collection of signals from sensors, switches, and operator devices directly into the control system, reducing wiring complexity and enhancing overall responsiveness.

The terminal also includes diagnostic capabilities via EtherCAT, providing engineers with clear insights into signal status and potential faults. This transparency helps reduce troubleshooting time and contributes to higher system availability.

In summary, the Beckhoff EL1008 is a reliable and efficient 8-channel digital input terminal for 24 V DC applications. With 3 ms input filters, EN 61131-2 compliance, low power consumption, and compact EtherCAT integration, it provides a robust and scalable solution for digital input acquisition. For businesses seeking cost-effective and space-saving I/O modules, the EL1008 delivers consistent performance in demanding automation environments.
