The EL3201-0020 is the factory calibrated version of the EL3201-0010. The EL3201-0020 analog input terminal facilitates the direct connection of a resistance sensor. 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 EL3201-00x0 can operate sensors in 4-wire technology, external bridges must be set for the 2- and 3-wire connection. This terminal must be operated using 4-wire technology for maximum accuracy. The EtherCAT Terminals indicate their measurement capability by means of light emitting diodes and status bits in the EtherCAT process image.

The EL3201-0020 is also available without calibration (EL3201-0010) or optionally with a DAkkS or ISO 17025 certificate (EL3201-0030) from an accredited service provider in cooperation with Beckhoff. The desired calibration certificate can be downloaded here using the unique identification number.
