The Beckhoff EL3314-0010 EtherCAT Terminal is a high-precision analog input module designed specifically for temperature measurement with thermocouples. With four independent channels, it allows direct connection of thermocouple sensors, making it an essential solution for applications requiring accurate thermal monitoring and control.

Equipped with a 24-bit resolution, the EL3314-0010 provides extremely fine-grained measurement capability. Depending on configuration, temperature values can be displayed with increments as small as 0.001°C per digit or at 10 nV per digit when measuring voltage. This precision ensures that even the smallest temperature variations are captured, making the terminal ideal for applications where exact temperature control is critical, such as in semiconductor production, pharmaceutical processes, or advanced research laboratories.

The module is designed to capture signals in the low-voltage range typical of thermocouples, supporting a measurement range of ±78 mV. With an integrated input filter limit frequency of 1 kHz, the EL3314-0010 effectively reduces noise and interference, ensuring reliable readings in electrically noisy industrial environments.

One of the standout features of the EL3314-0010 is its configurable conversion time. Users can adjust the terminal for different operating scenarios, ranging from fast updates at 5 ms per channel for dynamic processes, to slower but extremely stable measurements with a default of approx. 110 ms, or extended integration times up to 1.6 s for maximum precision. This flexibility allows the module to adapt to both fast-response control tasks and long-term monitoring applications.

Power for the terminal is supplied directly via the E-bus, simplifying wiring and integration into Beckhoff’s modular EtherCAT I/O system. Its compact design conserves valuable cabinet space, while status LEDs provide clear diagnostic feedback for each channel, supporting straightforward commissioning and maintenance.

The EL3314-0010 finds use across diverse applications. In process automation, it ensures reliable monitoring of temperature-critical processes such as chemical reactions or food production. In machine automation, it supports thermal control of heaters, extruders, or welding systems. In scientific and laboratory environments, its high resolution and stability make it ideal for precision experiments and environmental monitoring.

In summary, the Beckhoff EL3314-0010 EtherCAT Terminal is a powerful and flexible solution for high-precision thermocouple measurement. With four channels, 24-bit resolution, configurable conversion times, and a ±78 mV input range, it delivers the accuracy, stability, and adaptability required for demanding temperature measurement tasks in modern automation and research environments.
