ELX3152 | EtherCAT Terminal, 2-channel analog input, current, 0/4…20 mA, 16 bit, single-ended, Ex i

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 string must be terminated with one ELX9012 or two ELX9410.
