Crouzet Em4 temperature probe conection

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 ?


Hi imsgeneral,

Welcome to the Tech Forum.

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

Hello imsgeneral,

This feature appears unique to the Crouzet line of PLCs.

Picture of Crouzet EM4 PLC's input capabilities.

Yes, that is my understanding. Inputs 5 to 8 appear to accept the NTC sensor as shown in this installation guide excerpt. You will likely need to configure / program the I/O for the particular sensor.

Crouzet EM4 PLC analog connections.

Best Wishes,



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