The Beckhoff EL4002 EtherCAT Terminal is a compact and reliable analogue output module designed to generate precise voltage signals in industrial automation environments. With its two analogue output channels, the EL4002 provides flexible and accurate control signals for actuators, drives, and external devices that require a standardised 0…10 V input.

Each of the two channels delivers a voltage signal in the 0 to 10 V range, making the EL4002 ideal for setpoint generation in drives, proportional valve control, reference voltage supply, or analogue interfacing with measurement systems. With a 12-bit resolution, it ensures fine-grained signal output, enabling accurate adjustments and smooth operation in process and machine control tasks.

One of the standout features of the EL4002 is its support for EtherCAT distributed clock technology. With a synchronisation precision of better than 1 µs, it guarantees deterministic output timing across distributed systems. This makes the EL4002 particularly well suited for time-sensitive applications such as synchronised motion control, coordinated multi-axis machinery, or high-speed process automation where timing accuracy is critical.

The EL4002 is built for robust and dependable performance. Each output is short-circuit proof and capable of driving loads greater than 5 kΩ, ensuring reliable operation and protection against wiring faults or accidental overloads. Power is supplied via the 24 V DC power contacts, allowing for easy integration into modular EtherCAT systems while reducing cabling complexity.

As a member of the EtherCAT Terminal family, the EL4002 benefits from the scalability and modularity of Beckhoff’s I/O architecture. It can be seamlessly combined with other digital, analogue, and special-function terminals to build customised automation solutions. Its compact housing helps save valuable cabinet space while delivering high-precision functionality in a small footprint.

Practical applications of the EL4002 are wide-ranging. It is commonly used in machine building, for driving analogue actuators and positioning systems, or in process automation, for generating setpoints in temperature, flow, or pressure control loops. It is equally valuable in test benches and laboratory environments, where precise and reliable analogue voltage output is required for simulation and measurement tasks.

In summary, the Beckhoff EL4002 EtherCAT Terminal provides a robust, compact, and accurate solution for analogue signal generation. With two channels, 12-bit resolution, support for distributed clock synchronisation, and short-circuit-proof outputs, it is a versatile and dependable choice for engineers looking to implement precise analogue voltage control in modern automation systems.
