Introduction

High-precision 4 channel analog input terminal for thermocouples, with wire break detection

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 reference 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 by default to 0.01 °C/digit "high resolution".
• The assured accuracy applies to the following settings:
• 50 Hz filter
• 23 ± 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 is possible (cold junction compensation, from 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.
