EL3202 – BECKHOFF

EL3202 | EtherCAT Terminal, 2-channel analog input, temperature, RTD (Pt100), 16 bit
The EL3202 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 can operate sensors in 2- and 3-wire technology, for the 2-wire connection an external bridge is necessary. The EtherCAT Terminals indicate their measurement capability by means of light emitting diodes and status bits in the EtherCAT process image.
