EL3314-0020 | EtherCAT Terminal, 4-channel analog input, temperature, thermocouple, 24 bit, high-precision, factory calibrated
Thermocouple measurement with Beckhoff components: precise and fast
For demanding applications: calibrated analog inputs
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The EL3314-0020 analog input terminal allows four thermocouples to be connected directly. The EtherCAT Terminal circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal high-precision temperature measurement at the terminal. The EL3314-0020 can also be used for mV measurement.
The desired calibration certificate can be downloaded from here using the respective serial number.
