Beckhoff ELX3252 | EtherCAT Terminal, 2-channel analog input, potentiometer

The ELX3252 EtherCAT Terminal enables potentiometers located in hazardous

areas classified zone 0/20 or 1/21 to be connected directly. A stabilized power

supply via power contacts of the ELX9560 power supply terminal and the

ratiometric measurement of the input voltage offer the preconditions for

precise measurement. Potentiometers from 300 Ω to 40 kΩ can be connected

to the inputs and the maximum resistance value of the used potentiometer

can be stored in the terminal.

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.
