PF527 with THERMISTOR

2 posts in this topic

Hi all,

I have THERMISTOR connected directly to PF527  on AI pin 14-15. I am not sure how to do the scaling on Logix5000 and what is the equation that I need to use to trip my reading. 

can someone help me with this !

Thanks for your response in advance.

Pins 14 and 15 are for a 4 to 20ma analog input. You cannot connect a Thermistor directly to that input.(see pdf)

You could use a transmitter to convert the thermistor to a 4 to 20ma and then connect it.

I am not familiar with the software as I have never used it. So no help on the scaling.
