The Beckhoff EL4132 EtherCAT Terminal is a precision analog output module designed for generating voltage signals in automation and control systems. With two independent output channels, each capable of delivering signals in the -10 V to +10 V range, the EL4132 provides engineers with a compact and reliable solution for driving actuators, controllers, and devices requiring precise analog voltage control.

Equipped with 16-bit resolution, the EL4132 delivers finely graduated voltage outputs, ensuring smooth and accurate signal generation. The terminal achieves a measurement error of less than 0.1% relative to full scale, making it suitable for demanding applications where signal accuracy directly impacts process quality, such as motion control, test systems, or precision instrumentation.

A key feature of the EL4132 is its support for distributed clocks within the EtherCAT system. With synchronisation precision better than 1 µs, it enables highly deterministic output timing across multiple devices. This functionality is particularly valuable in systems requiring tight coordination, such as multi-axis machine control, synchronised drive systems, or test benches where exact signal alignment is essential.

The terminal is designed for robustness and reliability. Each channel can drive loads of greater than 5 kΩ, ensuring compatibility with a wide range of devices. Built-in short-circuit protection safeguards both the terminal and connected equipment, contributing to long-term system durability. Power for the terminal electronics is supplied via the E-bus, simplifying integration into Beckhoff’s modular EtherCAT platform and reducing wiring requirements.

The EL4132 is highly versatile and finds use in numerous industries. In process automation, it can generate control signals for actuators, valves, and converters. In machine automation, it provides precise voltage control for drives, sensors, or test signals. In laboratory and R&D environments, it enables the reproduction of reference signals and experimental conditions with high accuracy. The combination of high resolution, robust design, and synchronised timing ensures that the terminal meets the requirements of advanced control and monitoring systems.

Compact in size, the EL4132 enables efficient use of cabinet space while delivering dual-channel capability within one module. Diagnostic LEDs provide clear operational feedback, helping engineers monitor status and quickly troubleshoot potential issues. Its seamless integration with Beckhoff’s TwinCAT software further simplifies configuration, parameterisation, and diagnostics, reducing engineering effort and commissioning time.

In summary, the Beckhoff EL4132 EtherCAT Terminal is a high-precision analog output module for generating ±10 V signals. With two channels, 16-bit resolution, <0.1% error, distributed clock synchronisation, and robust load handling, it offers engineers a reliable and scalable solution for precise voltage output in modern EtherCAT-based automation systems.
