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 string must be terminated with one ELX9012 or two ELX9410.
