The Beckhoff EL3152 EtherCAT Terminal is a versatile analog input module designed for accurate acquisition of process signals in the 4…20 mA current range, the most widely used standard in industrial automation. With two single-ended input channels, it enables compact and efficient integration of sensors and transmitters into EtherCAT-based control systems.

Each channel provides 16-bit resolution, ensuring fine granularity and high accuracy in current measurement. This allows engineers to monitor and control process variables with precision, making the EL3152 suitable for applications ranging from energy management and building automation to process control and machine monitoring.

The module integrates a 5 kHz input filter, which helps suppress high-frequency noise and transient disturbances. This ensures that only valid signals are captured, resulting in stable and reliable data even in electrically noisy environments. Combined with the high resolution, this feature enables consistent monitoring of signals such as pressure, temperature, or flow transmitted via current loop sensors.

A significant advantage of the EL3152 is its support for distributed clocks within EtherCAT networks. This functionality enables precise time-stamped data acquisition, allowing synchronised operation across multiple devices. In applications such as multi-axis motion systems, synchronised logging, or coordinated process control, this ensures accurate correlation of measured values with system events.

The terminal has a typical internal resistance of 85 Ω plus diode voltage, designed to ensure accurate measurement while maintaining compatibility with common current loop devices. Its dielectric strength of up to 30 V provides protection against accidental overvoltage, enhancing reliability and safeguarding both the terminal and connected equipment.

Power is supplied via the E-bus, eliminating the need for external wiring and simplifying integration into modular I/O systems. Its compact design allows engineers to fit multiple terminals within control cabinets or distributed enclosures, enabling scalable and space-efficient system design.

The EL3152 is well suited for industries that require reliable and accurate current measurement. In process automation, it can interface with transmitters monitoring critical variables like pressure or flow. In machine automation, it supports feedback loops and condition monitoring. In building systems, it integrates environmental and energy sensors into the overall control platform.

In summary, the Beckhoff EL3152 EtherCAT Terminal provides two reliable analog input channels for 4…20 mA signals with 16-bit precision. With its high resolution, distributed clock synchronisation, robust protective features, and seamless integration into EtherCAT networks, it offers engineers a compact and dependable solution for accurate process signal acquisition in modern automation environments.
