The Beckhoff EL4134 EtherCAT Terminal is a high-precision, 4-channel analog output module engineered for generating voltage signals in demanding industrial automation environments. With an output range of ±10 V per channel, the EL4134 is ideally suited for applications requiring symmetrical analog signals, such as servo drive control, process regulation, and laboratory test systems.

Each channel offers 16-bit resolution (including sign), enabling finely detailed signal generation with smooth and accurate output levels. The module achieves an output error of less than 0.1% relative to the full-scale value, ensuring consistently high precision in both machine control and process automation tasks. This accuracy makes the EL4134 a dependable choice where signal integrity is critical to system performance.

A key feature of the EL4134 is its support for EtherCAT distributed clocks. This functionality allows outputs to be synchronised with microsecond-level accuracy (<< 1 µs) across the network. Such precision is vital in applications like advanced motion control, robotics, and coordinated multi-axis systems, where exact timing ensures smooth, efficient, and accurate operation.

Reliability is built into the design of the EL4134. The outputs are short-circuit proof and designed for loads with a resistance greater than 5 kΩ, providing robust protection in real-world operating conditions. Additionally, the module incorporates 500 V electrical isolation between the E-bus and signal voltage, safeguarding both the control system and connected devices against electrical interference and ensuring long-term operational stability.

The terminal draws its power directly from the E-bus, simplifying installation and integration into Beckhoff’s modular EtherCAT I/O system. Each of the four outputs is mapped directly into the process image, allowing seamless access by the control system without complex setup procedures. Its compact form factor ensures that high channel density can be achieved without consuming excessive cabinet space, making it efficient for applications where space is limited.

The ±10 V signal range supported by the EL4134 expands its flexibility beyond conventional 0…10 V outputs. This makes it well-suited for interfacing with equipment and systems that require bipolar voltage signals, including drives, actuators, and analog instrumentation. The ability to output both positive and negative voltages allows engineers to implement advanced control strategies and more dynamic system behaviour.

In practical use, the EL4134 is ideal for industries such as machine building, robotics, material handling, and process control. Its combination of high accuracy, fast synchronisation, and robust design ensures reliable performance in both standard automation tasks and advanced, precision-driven applications.

In summary, the Beckhoff EL4134 EtherCAT Terminal delivers precision, robustness, and flexibility in a compact analog output module. With four ±10 V outputs, 16-bit resolution, distributed clock synchronisation, and integrated electrical isolation, it provides a dependable foundation for high-performance industrial control systems.
