Beckhoff ELX3158 | EtherCAT Terminal, 8-channel analog input, current

The ELX3158 analog EtherCAT 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. 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.
