Beckhoff ELX3312 | EtherCAT Terminal, 2-channel analog input, temperature

The ELX3312 analog input terminals allow the direct connection of thermocouples

located in hazardous areas classified zone 0/20 or 1/21. The circuitry of the

ELX3312 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. Voltage measurement in the mV range is also

possible with the ELX3312.

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 segment must be terminated with one ELX9012. two ELX9410

or one EK1110. The use of two ELX9410 allows the use of EL terminals behind

ELX terminals. With the EK1110. the terminal segment can be continued via an

EtherCAT cable, for example to implement cable redundancy.
