NI 9217 with PT100 resistance thermometer connection details

[stevenixon81]

The Pt100 sensor is combined with the transmitter in one unit that's what the SEM206P is, and I have both 9208 and 9217 modules

Apologies but I am struggling to find an actual picture of the full unit, it is combined with a Pt100 sensor with the transmitter internally connected, so in effect all I have to connect up are the positive and negative terminals to somewhere??

[stevenixon81]

Again apologies for my mistake, the SEM206P is not the total unit, I have a SEM206P which is connected to a Pt100 sensor in a combiened unit with the postive and negative terminals to connect.

Really should read what I am writing before I post.

Than you have 2 Options, both of them will work.

1) Using PT100 + Transmitter : Use NI 9208 : Connect (+) coming from the SEM206P to Vsup of NI9208 (19), connect (-) coming from the SEM206P to AI0 of of NI9208 (1) . Then use the sample program of NI 9208.

2) Using PT100 only : Use NI 9217 : Remove the transmitter connections of the PT100 sensor, then you will have 3 wires: Red, white and white. Connect Red to RTD0+  (1), connect white to RTD0- (2), connect second white to COM (3) . https://www.ni.com/docs/en-US/bundle/374187f/resource/374187f.pdf

All working fine now, just connected the Pt100 without the transmitter wired in.

Thanks again for your help tcanger, greatly appreciated.

not to mention, we usually struggle at the most simplest point, and people called experts are those who failed the most.
