The Beckhoff EL4102 EtherCAT Terminal is a high-precision analogue output module designed to generate voltage signals for industrial automation tasks. With two independent output channels, the terminal offers compact, reliable, and flexible signal generation for controlling actuators, process equipment, and test systems.

Each channel provides an output range of 0…10 V, making the EL4102 suitable for a wide array of industrial devices, including proportional valves, analogue actuators, and signal conditioning equipment. Its ability to deliver finely tuned analogue voltages ensures smooth and accurate control across diverse automation applications.

A defining strength of the EL4102 is its 16-bit resolution (including sign), which allows extremely fine voltage adjustments. This high level of detail ensures precise analogue signal reproduction, critical for applications where control accuracy directly impacts process quality, such as dosing systems, precision motion tasks, or test environments. The terminal also achieves an output error of less than 0.1% relative to the end value, guaranteeing consistently reliable signal integrity.

For time-critical applications, the EL4102 integrates with EtherCAT distributed clocks, offering synchronisation with a precision significantly better than 1 µs. This capability is essential in advanced automation systems where deterministic timing is required, such as multi-axis motion control, robotics, or coordinated test sequences. By aligning outputs across the EtherCAT network, the EL4102 ensures precise and predictable control.

The module is designed for robust performance, with outputs that are short-circuit proof and specified for loads greater than 5 kΩ. This protection ensures long-term reliability and safeguards connected equipment in demanding industrial environments. Power for the module is supplied directly via the E-bus, simplifying system integration and reducing wiring complexity.

As part of Beckhoff’s modular EtherCAT I/O system, the EL4102 offers seamless integration into distributed control architectures. It can be combined with a wide range of digital, analogue, and specialty terminals, enabling engineers to tailor I/O configurations precisely to project requirements. Its compact terminal housing allows high channel density while conserving valuable control cabinet space.

When paired with TwinCAT automation software, the EL4102 supports straightforward configuration, monitoring, and diagnostics. Engineers can parameterise output channels, monitor performance, and quickly troubleshoot issues within a unified engineering platform. This simplifies commissioning and enhances system maintainability throughout the lifecycle.

In summary, the Beckhoff EL4102 EtherCAT Terminal is a high-resolution, dual-channel analogue output module designed for precision, reliability, and synchronisation. With 16-bit accuracy, <0.1% output error, and deterministic EtherCAT integration, it delivers the performance required for advanced process control, motion applications, and industrial testing, making it a versatile choice for modern automation systems
