The Beckhoff EL4104 EtherCAT Terminal is a compact and high-performance module designed for precise analog signal generation in industrial automation systems. Featuring four independent voltage outputs in the 0…10 V range, the EL4104 enables engineers to control actuators, drives, and other voltage-controlled devices with precision and reliability.

Each channel offers a 16-bit resolution (including sign), providing finely detailed and highly accurate analog signals. With an output error of less than 0.1% relative to the full-scale value, the EL4104 guarantees consistent performance across a wide range of applications. Whether used for process control, test systems, or machine automation, this terminal ensures that signals are reproduced with high fidelity.

The EL4104 supports distributed clocks, a powerful feature of EtherCAT that enables precise synchronisation across multiple terminals. With a synchronisation precision of better than 1 µs, the module ensures time-critical signals are aligned across the network, which is essential for advanced motion control and coordinated system tasks. This functionality allows the EL4104 to be integrated seamlessly into high-precision applications where timing accuracy is critical.

Robustness and durability are key attributes of the EL4104. Each output is short-circuit proof and designed for loads with a resistance of greater than 5 kΩ, providing reliable operation even under challenging conditions. This ensures long-term dependability in environments where accidental wiring faults or demanding loads may occur.

Power is supplied via the E-bus, simplifying wiring and integration within Beckhoff’s modular EtherCAT system. The terminal’s compact design allows four analog outputs to be delivered in a space-saving format, reducing cabinet size while maximising functionality. Outputs are mapped directly into the process image, making them immediately accessible to the control system without additional configuration.

The EL4104 is particularly well-suited for applications where multiple analog outputs are required in a compact form factor. Typical uses include generating control voltages for servo amplifiers, regulating process variables in industrial plants, or providing reference signals for laboratory or test environments. Its precision and stability make it ideal for any system requiring high-quality analog signal output.

Integration into the EtherCAT I/O ecosystem provides additional advantages. The EL4104 benefits from EtherCAT’s real-time performance, deterministic communication, and scalability. Engineers can easily expand systems by adding terminals like the EL4104 into existing EtherCAT networks without compromising performance or flexibility.

In summary, the Beckhoff EL4104 EtherCAT Terminal offers a reliable, accurate, and compact solution for analog voltage output. With its four channels, 16-bit resolution, low output error, and support for distributed clocks, it provides the performance and flexibility required for precise automation tasks across a wide range of industries.
