The Beckhoff EL4024 EtherCAT Terminal is a versatile analogue output module designed for precise and reliable current signal generation in industrial automation systems. Featuring four output channels, each delivering standardised 4…20 mA signals, the EL4024 provides a robust and compact interface for driving actuators, controllers, and other field devices in process and machine automation.

The use of the 4…20 mA current loop standard ensures compatibility with a wide range of industrial equipment, including proportional valves, variable speed drives, process controllers, and measuring devices. By offering four channels in a single module, the EL4024 achieves high channel density while conserving valuable cabinet space, making it an efficient choice for engineers designing complex control systems.

Each channel delivers analogue outputs with 12-bit resolution, enabling fine granularity and smooth signal transitions. Combined with the support for EtherCAT distributed clock technology, the EL4024 ensures synchronisation precision of << 1 µs across outputs. This deterministic timing makes it particularly well suited for applications requiring coordinated analogue control, such as synchronised process regulation, multi-axis actuation, or test and measurement environments where exact timing is essential.

The module is engineered for reliability and durability in industrial environments. Each output channel is short-circuit proof and designed to drive loads up to 350 Ω, ensuring safe operation even under challenging conditions or wiring errors. Power is supplied via 24 V DC power contacts, simplifying integration into modular EtherCAT I/O systems and reducing wiring effort.

As part of the EtherCAT Terminal system, the EL4024 offers seamless integration with digital, analogue, and special-function terminals. This modular approach allows engineers to build tailored I/O configurations that match the specific needs of their application, whether in machine automation, process control, or decentralised I/O installations.

Typical use cases include process automation, where the EL4024 provides precise setpoint values for controlling pressure, temperature, or flow; machine automation, where it drives proportional actuators or analogue-controlled devices; and test and measurement systems, where synchronised current outputs are essential for simulation and calibration tasks. Its versatility ensures broad applicability across industries such as manufacturing, packaging, building automation, and energy systems.

In summary, the Beckhoff EL4024 EtherCAT Terminal offers a compact, accurate, and reliable solution for analogue current output. With four channels delivering 4…20 mA signals, 12-bit resolution, distributed clock support, and robust short-circuit protection, it provides engineers with a dependable module for precise and synchronised analogue control in modern automation systems.
