The Beckhoff EL4032 EtherCAT Terminal is a versatile and compact analog output module designed to generate precise voltage signals for industrial automation systems. With two independent output channels, each capable of delivering signals in the -10 V to +10 V range, it provides engineers with the flexibility to control actuators, drives, and process devices that rely on voltage-based control.

Each channel is equipped with 12-bit resolution, ensuring smooth and accurate signal output. The terminal guarantees an output error of less than 0.1% relative to the full-scale value, making it suitable for demanding applications where precision is essential. This level of accuracy ensures reliable performance in areas such as machine automation, process control, test stands, and laboratory environments.

The EL4032 supports EtherCAT distributed clocks, offering synchronisation precision of less than 1 µs. This enables highly accurate timing across multiple devices in the EtherCAT network, which is vital in motion control systems, robotics, and applications requiring tight coordination between analog outputs and other control signals.

Designed for industrial reliability, the EL4032 provides short-circuit proof outputs and is suitable for loads greater than 5 kΩ. This robustness ensures long-term performance and safety in demanding environments. Power is supplied via the 24 V DC power contacts, while integration into the EtherCAT network is seamless, with all output values mapped directly into the process image for easy access and configuration through Beckhoff’s TwinCAT software.

The terminal’s compact design allows for high channel density, reducing control cabinet space requirements while maintaining system scalability. As part of the Beckhoff EtherCAT I/O system, the EL4032 can be combined with a wide range of digital, analog, and specialty terminals, providing engineers with maximum flexibility in designing modular automation architectures.

Typical applications include generating reference voltages for servo drives, proportional valves, or instrumentation equipment. It is also widely used in test and measurement systems where accurate voltage outputs are required to simulate signals, drive sensors, or provide controlled excitation to circuits. Its fast response and integration with distributed clocks make it particularly valuable in synchronised processes and real-time control tasks.

In summary, the Beckhoff EL4032 EtherCAT Terminal is a precise, reliable, and synchronisation-ready analog output module. With its two ±10 V output channels, 12-bit resolution, <0.1% error rate, and support for distributed clocks, it delivers the accuracy and robustness needed for advanced automation systems across industries.
