Beckhoff ELX3152 | EtherCAT Terminal, 2-channel analog input, current, 0/4…20 mA

The ELX3152 analog input terminal allows the direct connection of

intrinsically safe field devices located in hazardous areas classified

zone 0/20 or 1/21. It supplies measuring transducers located in

the field and transmits their analog measuring signals electrically

isolated to the automation device. 

The measuring range can be switched between 0...20 mA and 4...20

mA by software. With a technical measuring range of ±107% of the

nominal range, the terminal also supports commissioning with sensor

values in the limit range and evaluation according to NAMUR NE43.

The error LEDs indicate an overload condition and wire breakage.

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.
