EL3314-0030 | EtherCAT Terminal, 4-channel analog input, temperature, thermocouple, 24 bit, high-precision, externally 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 EL3314-0030 analog input terminal allows four thermocouples to be connected directly. The 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 internal high-precision temperature measurement at the terminal. The EL3314-0030 can also be used for mV measurements.
The individual calibration certificate for each device, in accordance with ISO 17025 or DAkkS, depending on the device variant, can be downloaded here. These calibration certificates are issued for Beckhoff by an accredited service provider. Recalibration on request.
