Beckhoff ELX3204 | EtherCAT Terminal, 4-channel analog input, temperature

The ELX3204 analog input terminal allows the direct connection of RTDs

located in hazardous areas classified zone 0/20 or 1/21.

The circuitry of the ELX3204 can operate sensors with 2-wire technology.

Linearization is carried out over the entire freely selectable temperature

range. By default the terminal is set to Pt100 sensors with 2-wire

technology. The ELX3204 terminal indicates signal state and sensor

malfunctions (e.g. wire breakage) by means of LEDs.

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.
