Crouzet Em4 temperature probe conection

[imsgeneral]

good day , i need help with the connection of a 10 k ohm NTC thermistor on a Em4

as I understand it, one lead goes to Em4 power supply and the other to I5 -i8 correct ?

thanks

Hi imsgeneral,

Welcome to the Tech Forum.

Can you give a specific part number to help check into your question?

I may be misreading this, but it looks to me like it works from I5 through IC.

Crouzet Programmable Logic Controller Thermistor Selection

Several customers have asked about the matching thermistors to Crouzet Programmable Logic Controllers (PLC) such as the EM4 and Millenium Slim. The electrical connections for the thermistor are clearly presented in the associated datasheet for the EM4 and Millenium Slim. The thermistor selection is also clearly presented in the Crouzet-Soft tool under the APP tab as shown here. This software feature reflects Crouzet’s design philosophy of simplifying the user interface. This is like the Arduino…
