The Beckhoff EL4014 EtherCAT Terminal is a versatile analog output module designed for precise current signal generation in industrial automation systems. With four independent output channels, it provides engineers with a compact and reliable way to control actuators, converters, or other current-driven devices directly from an EtherCAT network.

Each channel can generate signals in the standard range of 0…20 mA, ensuring compatibility with the majority of industrial devices such as proportional valves, I/P converters, and current-controlled drives. With a 12-bit resolution, the EL4014 ensures finely graded signal output, enabling accurate control over process variables in applications like dosing, speed regulation, or actuator positioning.

A standout feature of the EL4014 is its support for distributed clocks, allowing the outputs to be precisely synchronised with other terminals and devices in the EtherCAT system. With sub-microsecond precision (<1 µs), the module ensures that signals are delivered in exact alignment with system timing requirements. This is particularly valuable in high-performance applications such as coordinated multi-axis motion, synchronised process control, or test and measurement setups where accurate timing is critical.

The terminal is designed to handle loads of up to 350 Ω per channel, providing flexibility for interfacing with a wide range of actuators and instruments. Short-circuit protection is built in, safeguarding both the terminal and connected devices, while maintaining reliable operation under demanding industrial conditions.

Power is supplied to the EL4014 via 24 V DC through the power contacts, simplifying integration into standard control cabinet infrastructures. As part of Beckhoff’s modular EtherCAT I/O platform, the terminal can be combined seamlessly with digital, analog, and communication modules, supporting scalable and tailored I/O architectures.

The EL4014 is widely applicable across industries where precise analog current control is required. In process automation, it can drive current loops for controlling valves, pumps, or actuators. In machine automation, it provides smooth current control for devices such as proportional drives or dosing systems. In laboratory and test systems, its synchronised outputs make it ideal for generating reference signals or conducting performance validation tasks.

By integrating multiple output channels into a single compact terminal, the EL4014 reduces system footprint and simplifies wiring compared to external analog output modules. Diagnostic LEDs provide quick visual feedback, helping engineers to monitor operational status and troubleshoot issues efficiently.

In summary, the Beckhoff EL4014 EtherCAT Terminal delivers compact, reliable, and synchronised analog current outputs. With four channels, 0…20 mA range, 12-bit resolution, distributed clock capability, and robust short-circuit protection, it offers engineers a flexible and high-performance solution for precise current control in modern automation environments.
