ELX3314 | EtherCAT Terminal, 4-channel analog input, temperature, thermocouple, 16 bit, Ex i
The system-integrated solution for explosion protection: PC-based control
The 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. Linearization 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.
EtherCAT terminals of the ELX series must always be operated in conjunction with the ELX9560 power supply terminal. This terminal generates an electrically isolated output voltage (24 V EX) from the input voltage (24 V DC) for supplying the subsequent ELX terminals. If a new power supply is required, the combination of an ELX9410 and an ELX9560 can be used so that further ELX terminals can be added. The ELX terminal string must be terminated with one ELX9012 or two ELX9410.
