The Beckhoff EL3002 EtherCAT Terminal is a compact and efficient analog input module that provides two channels for voltage measurement in the ±10 V range. Designed for industrial automation applications requiring reliable monitoring of analog signals, it offers 12-bit resolution and robust signal conditioning, making it a dependable component for a wide variety of process and control systems.

Each of the two single-ended input channels allows flexible connection to analog signal sources such as sensors, transducers, or control voltages from other equipment. The 12-bit resolution ensures adequate precision for most standard automation applications, providing detailed representation of input signals while maintaining fast processing performance. The terminal’s conversion time of 0.625 ms (default) enables quick acquisition of measurement values, with the option of configuring multiplexed operation for tailored performance to suit system requirements.

The EL3002 features an internal resistance greater than 130 kΩ, ensuring minimal loading on signal sources and maintaining the integrity of the measured voltage. Its built-in 1 kHz input filter provides effective suppression of unwanted noise and interference, enabling stable, clean signal capture in demanding industrial environments. With a dielectric strength of up to 30 V, the module offers protection against accidental overvoltage, enhancing safety and extending the lifetime of both the terminal and connected devices.

Integration into an EtherCAT system is straightforward thanks to power supply via the E-bus, which simplifies wiring and reduces system complexity. This modular approach aligns with Beckhoff’s philosophy of building scalable, adaptable I/O systems that can be easily expanded as project requirements evolve.

The EL3002 is particularly well suited to applications such as monitoring analog process signals, recording sensor outputs, or interfacing with control voltages in machine automation. For example, it can be used to acquire input from pressure or flow sensors, read analog reference signals, or track voltage variations in test and measurement setups. Its balance of speed, precision, and compact size makes it a versatile tool for both simple control systems and more complex automation architectures.

By combining compact design, fast conversion times, and robust electrical characteristics, the Beckhoff EL3002 delivers dependable analog measurement performance. It is an ideal solution for engineers and integrators seeking a cost-effective, reliable, and easy-to-implement analog input module within the EtherCAT ecosystem.
