Introduction

Fig. 16: EL3314-0010

High-precision 4 channel analog input terminal for thermocouples, with open-circuit recognition

The EL3314-0010 analog Input Terminal enables direct connection of thermocouples. Compared with the standard EL3314 model, it offers significantly more precise temperature measurements thanks to improved measuring circuit and more precise cold junction measurement. Otherwise the EL3314-0010 behaves similar to the EL3314.

For high-precision measurements please note the following:

• Before delivery the EL3314-0010 is calibrated against a high-precision reference voltage

• The terminal is set to 0.01°C/digit ("high resolution") as standard

• The assured accuracy applies to the following settings:

◦ 50 Hz filter

Product overview

◦ 25 ± 5 °C ambient temperature

◦ horizontal installation position

• In addition it has the following features

◦ an additional software-based "MC filter" can be used for smoothing the measured value

◦ external cold junction compensation (reference junction compensation is possible since FW03)

• We advise against the use of compensation wires, because they reduce the measuring accuracy of the

EL3314-0010

• We recommend using thermocouples with suitable accuracy
