Introduction

4-channel analog input, temperature, RTD (Pt100), 16 bit, 3-wire connection

The analog input terminal EL3214 allows the direct connection of four resistance sensors in 3-wire technology on 12 mm width (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 done in the terminal according to different sensor characteristics (Pt100, Pt1000, Ni120, Ni1000, KTY types and others).

The EL3214 can operate sensors in 2- and 3-wire technology.

The EtherCAT Terminals indicate their measurement capability via LEDs and status bits in the EtherCAT process image.
