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.

For the EL3314-0030, an individual calibration certificate is available, currently as a choice of DAkkS or IS0 17025-compliant certificate. The certificate is issued by an accredited service provider in collaboration with Beckhoff.

The desired calibration certificate can be downloaded from here using the respective serial number.
