Beckhoff Automation elx3204

The ELX3204 analog input terminal allows the direct connection of RTDs located in hazardous areas classified zone 0/20 or 1/21. The circuitry of the ELX3204 can operate sensors with 2-wire technology. Linearization is carried out over the entire freely selectable temperature range. By default the terminal is set to Pt100 sensors with 2-wire technology. The ELX3204 terminal indicates signal state and sensor malfunctions (e.g. wire breakage) by means of LEDs.   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.
