EL3202-0020 | EtherCAT Terminal, 2-channel analog input, temperature, RTD (Pt100), 16 bit, high-precision, factory calibrated
For demanding applications: calibrated analog inputs
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The EL3202-0020 is the factory calibrated version of the EL3202-0010. The EL3202-0020 analog input terminal facilitates the direct connection of two resistance sensors. 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 EL3202-0020 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 individual Beckhoff factory calibration certificate can be downloaded here for each device. Recalibration (ZS9001) is possible via Beckhoff Service.
