The Beckhoff EL3062 is a 2-channel analog input EtherCAT Terminal designed for the accurate acquisition of single-ended voltage signals. Supporting a measurement range of 0…10 V, it provides reliable signal capture for industrial automation tasks, from process monitoring to machine control. Its compact dual-channel design offers both efficiency and performance within Beckhoff’s modular EtherCAT I/O system.

Each of the two input channels is designed to capture single-ended voltage signals with a high internal resistance (> 130 kΩ), ensuring minimal loading of the connected sensor or source. This feature preserves signal integrity, making the EL3062 suitable for sensitive measurement tasks where accuracy is essential. With a dielectric strength of up to 30 V, the inputs are well protected against overvoltage, adding robustness to real-world applications where transients or wiring errors may occur.

The EL3062 delivers 12-bit resolution for signal conversion, providing fine granularity across the 0…10 V input range. The data is presented in a 16-bit format, including sign, to ensure consistent integration with the EtherCAT communication structure. This resolution is more than sufficient for applications where precise process values or control variables must be monitored, such as in energy systems, motion applications, or quality control processes.

Speed is another strength of the EL3062. With a default conversion time of 0.625 ms, it supports fast acquisition of analog signals, enabling real-time responsiveness in control systems. The multiplexed design also allows configuration of conversion timing to balance speed with other system requirements. This flexibility ensures the terminal can be tailored to specific application needs, from high-speed control loops to slower process monitoring tasks.

The terminal is powered via the E-bus, simplifying integration into existing EtherCAT assemblies without requiring separate power connections. Its compact size conserves DIN rail space while still offering dual-channel functionality, making it ideal for high-density control cabinet layouts.

Practical applications for the EL3062 are diverse. In machine automation, it can be used to capture reference or feedback voltages from drives, sensors, or actuators. In process automation, it can monitor setpoints, analog transducers, or control signals for pumps and valves. In building or energy systems, it can track voltage outputs from sensors or measurement devices to support system optimisation and monitoring.

In addition, the EL3062 benefits from EtherCAT’s deterministic, real-time communication. Measured values are transmitted directly into the process image of the controller with minimal latency, supporting precise and synchronised control strategies.

In summary, the Beckhoff EL3062 is a compact and reliable dual-channel analog input terminal for 0…10 V voltage signals. With 12-bit resolution, configurable conversion times, high input resistance, and robust overvoltage tolerance, it provides accurate and dependable signal acquisition. Seamlessly integrated into Beckhoff’s EtherCAT I/O system, the EL3062 delivers flexibility and performance for a wide range of industrial automation applications.
