The system-integrated solution for explosion protection: PC-based control

The system-integrated solution for explosion protection: PC-based control

The ELX1054 digital input terminal acquires signals from NAMUR field devices according to EN 60947-5-6. The sensors are supplied with a voltage of 8.2 V and return a diagnosable current signal. In this way, a wire breakage or short-circuit can be detected in addition to the switching state. The LEDs indicate signal or any error states, channel by channel.

Using a DIP switch on the side, it is possible to select channel by channel whether a positive switching or negative switching sensor is to be connected. Thus, no changes to the PLC are required for the connection of both NAMUR break contacts or make contacts.

 

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.
