The Beckhoff EL4008 EtherCAT Terminal is an eight-channel analogue output module engineered for efficient and precise signal generation in automation systems. Designed to output voltage signals in the range of 0…10 V, it provides engineers and system designers with a versatile tool for controlling actuators, analogue devices, and process equipment in industrial environments.

With eight independent outputs, the EL4008 delivers a high channel density in a compact form factor. This makes it particularly advantageous for applications requiring multiple analogue control signals without consuming excessive cabinet space. Each channel provides finely tuned analogue outputs, ideal for driving proportional valves, analogue actuators, measurement equipment, and process control devices.

The module’s 12-bit resolution ensures precise analogue signal reproduction, allowing for accurate control across the full 0…10 V range. Combined with EtherCAT’s distributed clock technology, the EL4008 can synchronise outputs with a precision of significantly less than 1 µs. This deterministic timing is critical for motion control, robotics, test benches, and any application requiring tightly coordinated multi-channel analogue output.

Robust performance is further ensured by the EL4008’s load handling capacity. Designed for loads greater than 5 kΩ, each output is short-circuit proof, guaranteeing safe operation even under fault conditions. This reliability helps protect both the terminal and connected devices, reducing downtime and maintenance in demanding automation environments.

The terminal is powered directly via the 24 V DC power contacts, simplifying system wiring and eliminating the need for separate supply units. Its seamless integration into Beckhoff’s modular EtherCAT I/O system ensures straightforward scalability, allowing engineers to combine the EL4008 with a wide range of digital, analogue, and specialty terminals to create a tailored control solution.

As part of the EtherCAT ecosystem, the EL4008 benefits from high-speed, deterministic communication and easy configuration through TwinCAT automation software. This integration allows users to parameterise channels, monitor status, and implement diagnostics efficiently, reducing engineering effort and improving system transparency.

Compact, reliable, and versatile, the EL4008 is well-suited for diverse automation applications. From controlling analogue actuators in process automation to generating synchronised test signals in laboratory environments, it offers both the precision and robustness needed for modern industrial systems.

In summary, the Beckhoff EL4008 EtherCAT Terminal combines high channel density, precision analogue output, and EtherCAT synchronisation in a compact module. Its short-circuit protection, deterministic timing, and seamless integration make it a dependable choice for engineers seeking efficient, scalable, and accurate analogue output solutions.
