Introduction

4-channel analog input, temperature, RTD/NTC, 16 bit

The EL3204-0200 analog input terminal allows the direct connection of four resistance sensors up to 240 kΩ in the 2-wire connection, so that a significantly increased measuring range is available compared to the EL320x-0000 and thus the use of high-resistance NTC sensors is possible.

The measured resistance value can either be output directly in ohms or immediately transformed into a temperature in the terminal. In the second case, the conversion from resistance to temperature can be performed either according to selectable characteristic curves (Pt1000, Ni1000, various NTC types), conversion formulas with specific material parameters (e.g. according to IEC 60751, Steinhart-Hart equation, B parameter equation) or according to a freely programmable conversion table.

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