The Beckhoff EL3314-0090 is a high-precision 4-channel analog input terminal designed for the direct connection of thermocouples within an EtherCAT I/O system. It linearizes the voltage values over the entire temperature range, specific to the thermocouple type, and outputs the temperature in a convenient format (0.1 °C resolution). This terminal features integrated cold junction compensation and open-circuit detection for enhanced reliability. The -0090 variant is distinguished by the inclusion of a factory calibration certificate, making it ideal for applications requiring verifiable accuracy and high-quality temperature measurement.
