ELX3314 | 4-channel input terminal thermocouple/mV measurement, 2-wire connection, 16 bit, Ex i

ExThe ELX3314 analog input terminals allows the direct connection of thermocouples located in hazardous areas classified Zone 0/20 or 1/21. The circuitry of the ELX3314 can operate sensors with 2-wire technology. Linearisation is possible over the entire freely selectable temperature range. The error LEDs indicate a broken wire. Compensation for the cold junction is achieved through internal temperature measurement. Millivolt measurement is also possible with ELX3314.
