The Beckhoff EL3356-0010 EtherCAT Terminal is a high-precision analogue input module specifically designed for acquiring signals from measuring bridges in full-bridge technology. With its exceptional 24-bit resolution, wide measurement range, and integrated distributed clock support, the EL3356-0010 is an ideal solution for demanding measurement applications such as force, torque, weight, and pressure monitoring.

The terminal features two inputs that together connect to a single full-bridge sensor, such as a strain gauge or load cell. It supports a maximum differential input voltage (UD) of ±27 mV, which is well suited for low-level sensor signals commonly used in precise measurement systems. Additionally, the reference voltage input (UREF) can accommodate up to ±13.8 V, ensuring compatibility with a wide range of sensor excitation voltages. The design includes high internal resistance values (> 1 MΩ for UD and > 200 kΩ for UREF), ensuring minimal loading of the connected sensor and preserving signal accuracy.

A key feature of the EL3356-0010 is its high-resolution measurement capability. With 24-bit conversion, the terminal delivers extremely fine measurement detail, capable of resolving signal changes down to 0.01 µV/V. This makes it especially valuable in applications requiring precise detection of minute variations, such as weighing processes, tension monitoring, or high-precision test setups. While it supports all nominal sensitivities, a recommended range of 0.5…4 mV/V ensures optimal performance and noise rejection.

To guarantee reliable results in real-time environments, the EL3356-0010 is equipped with EtherCAT distributed clock functionality, enabling time-synchronised data acquisition across multiple channels and terminals. This is essential for applications requiring multi-axis measurement synchronisation or highly coordinated motion and monitoring tasks. Combined with a 10 kHz low-pass filter (-3 dB), the terminal ensures accurate signal capture with effective noise suppression, even in electrically noisy environments.

Integration into EtherCAT systems is seamless, as the EL3356-0010 communicates directly with the control system via the E-bus. This provides deterministic data exchange with minimal latency, enabling real-time monitoring and closed-loop control. Its compact form factor allows engineers to implement high-precision measurement capabilities without compromising cabinet space or modularity.

The EL3356-0010 is ideally suited for weighing technology, force measurement in mechanical systems, torque monitoring in rotating machinery, and precision laboratory instrumentation. Its ability to process full-bridge sensor signals with high accuracy and synchronisation makes it a cornerstone for applications where measurement precision is critical to quality, safety, and performance.

In summary, the Beckhoff EL3356-0010 EtherCAT Terminal delivers uncompromising precision and reliability for bridge-based sensor measurement. With 24-bit resolution, wide measurement ranges, distributed clock synchronisation, and robust filtering, it provides a powerful and flexible solution for engineers seeking high-accuracy analogue acquisition in advanced automation and test environments.
