Measurement technology simply integrated: With the analog EtherCAT Terminals.

The EL3218 analog input terminal facilitates the direct connection of eight resistance sensors using 3-wire technology over a width of 24 mm (high-density housing). The measured resistance value can either be output directly in ohms or transformed into a temperature. If the temperature at the measuring point is of interest, the conversion from resistance to temperature can be carried out in the terminal according to various sensor characteristics (Pt100, Pt1000, NI120, NI1000, KTY types, etc.). The EL3218 can operate sensors using 2-wire and 3-wire technology. The EtherCAT Terminals indicate their measurement capability by means of light emitting diodes and status bits in the EtherCAT process image.
