The Beckhoff EL3164 EtherCAT Terminal is a versatile analog input module designed to acquire up to four single-ended voltage signals in the 0…10 V range with high resolution and reliability. Compact and efficient, this terminal provides a cost-effective solution for integrating multiple analog inputs into EtherCAT-based automation systems while maintaining precision and robustness.

With its 16-bit resolution, the EL3164 ensures fine-grained signal acquisition, making it suitable for capturing even small changes in process values. This accuracy is essential in applications such as closed-loop control, process monitoring, and measurement tasks, where signal fidelity directly impacts system performance.

The terminal is designed for robust signal acquisition, featuring an internal resistance greater than 200 kΩ to minimise loading effects on connected devices. A dielectric strength of up to 30 V provides added protection against overvoltage, safeguarding both the terminal and sensors from potential damage due to wiring errors or transient conditions.

An input filter limit frequency of 5 kHz ensures that the module can handle dynamic signals while effectively reducing noise. This combination of speed and stability allows engineers to configure the terminal for applications ranging from fast-response monitoring to stable long-term measurements, balancing performance with reliability.

As part of the EtherCAT I/O system, the EL3164 integrates seamlessly into distributed automation networks. The inclusion of distributed clocks enables precise time-stamping and synchronisation of data across the EtherCAT system, ensuring deterministic behaviour and reliable coordination with other I/O modules, motion axes, and controllers. This is particularly valuable in applications that demand precise synchronisation, such as motion control or high-speed production lines.

The EL3164 is powered via the E-bus, eliminating the need for additional wiring of the electronics supply and simplifying installation. Its slim housing design conserves valuable cabinet space, while integrated status LEDs provide quick visual feedback on channel activity and terminal status, easing commissioning and maintenance tasks.

The terminal is widely applicable across industries. In machine automation, it can acquire voltage signals from position sensors, potentiometers, or converters. In process automation, it is ideal for monitoring transducer outputs such as pressure or flow. In building automation, it can be used for integrating analog inputs like environmental sensors into control systems.

In summary, the Beckhoff EL3164 EtherCAT Terminal is a compact, high-precision, and robust analog input module for acquiring up to four 0…10 V signals. With 16-bit resolution, distributed clocks, robust electrical design, and flexible input filtering, it delivers reliable, synchronised, and accurate voltage acquisition for a wide range of automation applications.
