The ELX5151 EtherCAT Terminal allows the direct connection of an intrinsically safe incremental encoder from zone 0/20 and 1/21 hazardous areas. The terminal supplies the encoder with 8.2 V DC and evaluates a diagnostic-capable NAMUR signal according to IEC 60947-5-6. In this way, a wire breakage or short circuit can be detected in addition to the switching state. The ELX5151 can also be used as an up/down counter and allows switching between 16- and 32-bit counting.
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.
