Beckhoff EtherCAT Terminal, 4-channel Analog Input, Temperature - EL3314
The EL3314 analog input terminal facilitates direct connection of up to four thermocouples. It utilizes EtherCAT Terminal technology to operate thermocouple sensors via a 2-wire technique. Linearization across the entire temperature range is managed by an onboard microprocessor, offering flexible temperature range selection. Error LEDs signal any wire breakages, ensuring reliable operation. Cold junction compensation is achieved through internal temperature sensing at the terminal. Additionally, the EL3314 supports mV measurements, enhancing its versatility in industrial applications requiring precise temperature sensing and analog signal acquisition.
