The Beckhoff EL4001 is a compact EtherCAT Terminal designed to generate precise analog output voltages for automation and control applications. With its 0…10 V output range, high resolution, and integrated EtherCAT Distributed Clock support, it delivers reliable and accurate signal generation for a wide variety of industrial processes.

As a single-channel analog output module, the EL4001 is ideal for applications where a dedicated control signal is required. The 0…10 V range is widely adopted across automation, making the terminal suitable for driving actuators, regulating variable-speed drives, controlling setpoints for process equipment, or interfacing with third-party controllers and instrumentation.

The terminal features 12-bit resolution, ensuring fine-grained voltage output. This resolution enables precise control, particularly in applications where small changes in voltage directly influence performance, such as in dosing systems, motion control, or energy regulation. With an output error of less than 0.1% relative to full scale, the EL4001 guarantees a high level of accuracy and repeatability, ensuring stable process operation and quality results.

Timing is a critical aspect of analog signal generation, and the EL4001 excels by supporting EtherCAT Distributed Clocks. With sub-microsecond precision (<< 1 µs), the terminal can synchronise output signals precisely with other system events. This deterministic timing is especially valuable in applications such as synchronised multi-axis systems, coordinated machine processes, or test and measurement setups where exact timing is essential.

Reliability is built into the terminal’s design. The EL4001 is short-circuit proof, protecting both the terminal and connected devices from accidental wiring errors or overload conditions. It supports load impedances greater than 5 kΩ, ensuring compatibility with a wide range of external devices without compromising output stability.

Power for the terminal is supplied via 24 V DC power contacts, integrating seamlessly into Beckhoff’s modular EtherCAT I/O system. Its compact format allows efficient use of DIN rail space, while modularity ensures that it can be easily combined with digital, analog, or communication terminals to create a tailored I/O configuration for each application.

Practical applications of the EL4001 span across industries. In manufacturing, it can provide control signals for variable actuators or servodrives. In process automation, it can regulate setpoints for valves, pumps, or temperature controllers. In test environments, it enables precise signal generation for simulating or controlling measurement devices. Wherever a stable and accurate voltage output is required, the EL4001 provides a dependable solution.

In summary, the Beckhoff EL4001 is a robust and precise 1-channel analog output terminal for 0…10 V signals. With 12-bit resolution, high accuracy, Distributed Clock synchronisation, and short-circuit protection, it offers the performance and reliability needed for demanding automation tasks. Compact and modular, the EL4001 integrates seamlessly into EtherCAT systems, supporting efficient and flexible system design.
