The Beckhoff EL3054 EtherCAT Terminal is a compact, high-performance analog input module designed for capturing current signals in the standard 4…20 mA range. With four single-ended input channels, it enables efficient signal acquisition from industrial sensors, transmitters, and actuators, making it particularly suitable for process automation, machine monitoring, and data logging applications.

Each channel provides a 12-bit resolution, with data presented in a 16-bit format including sign for compatibility and clarity within control systems. This ensures accurate and reliable representation of measurement values, even in demanding applications. With its compliance to the 4…20 mA standard, the EL3054 seamlessly integrates with widely used current loop transmitters, ensuring compatibility across a variety of devices and industries.

The terminal offers a default conversion time of 0.625 ms, allowing rapid signal acquisition in time-sensitive applications. For added flexibility, conversion times are configurable and operate in a multiplexed mode, enabling users to balance speed and measurement stability according to their process requirements. This adaptability makes the EL3054 suitable for both high-speed machine control tasks and slower, noise-sensitive process monitoring.

The EL3054 is designed with robust input circuitry that ensures stable and consistent measurements. Each channel features an internal resistance of approximately 85 Ω, with a 1 kHz input filter to suppress high-frequency noise. This combination ensures reliable operation even in electrically noisy environments. Additionally, the module offers a dielectric strength of up to 30 V, providing protection against transient voltages and enhancing long-term reliability in industrial environments.

Power is supplied via the EtherCAT E-bus, allowing seamless integration into Beckhoff’s modular I/O system. All measurement data is mapped directly into the controller’s process image, enabling real-time access without complex configuration. This plug-and-play functionality reduces commissioning time and simplifies system expansion, making the EL3054 a cost-effective choice for scalable automation systems.

By consolidating four current input channels into one compact terminal, the EL3054 offers excellent channel density, saving valuable cabinet space and reducing wiring effort. Its design supports efficient deployment in distributed control architectures, ensuring flexibility for a wide variety of system layouts.

Typical applications include process monitoring (e.g., flow, pressure, and temperature sensors with 4…20 mA transmitters), machine building, and building automation where multiple analog signals must be measured simultaneously. Its accuracy, fast conversion, and noise immunity make it a dependable choice in industries where precision and robustness are essential.

In summary, the Beckhoff EL3054 EtherCAT Terminal is a compact, accurate, and versatile analog input module. With four 4…20 mA channels, 12-bit resolution, configurable conversion times, and robust protective features, it provides a reliable solution for modern automation systems seeking efficient analog signal acquisition.
