Beckhoff ELX3202 | EtherCAT Terminal, 2-channel analog input, temperature

The ELX3202 analog input terminal allows the direct connection of RTDs

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

The circuitry of the ELX3202 can operate sensors with 2-, 3- and 4-wire

technology. Linearization is carried out over the entire freely selectable

temperature range. By default the terminal is set to Pt100 sensors with

3-wire technology. The ELX3202 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.
