Connector Block CB-68LPR

[Onga]

Hello everyone!

I am trying to connect many Type-K thermocouples to this connector block. I've connected only one (+ve wire of thermocouple is in screw J68 and -ve is in J34). I measure temperature using VI Logger, channel 0 and it warks perfectly!

BUT I want to connect as many thermocouples as possible! I need help in: what screws to use for other thermocouples, how to connect the rest of them? What combination to use with channels on VI Logger and screws used?

Thanks!

Regards Slav.

Hi,

This depends mainly on what kind of data acquisition card you are using. You can find the pinouts by going to Measurement & Automation explorer and going to Help >> Help Topics >> Traditional NI-DAQ. In this document, the pinouts are listed for Traditional NI-DAQ Device Terminals >> Multifunction DAQ. It sounds like you have a 68-pin MIO board, so this lists the pinouts for the entire board.

Keep in mind, you also can also use RSE mode and get 16 channels. You would connect the V+ wire to your CH(x) and your V- wire to AIGND. Be sure to set this configuration in MAX so that you can obtain a valid reading.

Hope this helps!

This is the only diagram that I could find on website about 68LPR. Thus I don't know which pin is a CH and which one is a AIGND. If it's not much trouble can you list me some combinations on how to connect thermocuples to this pins?

So far I've got (it works perfect):

Pin J68 +ve
Pin J34 -ve (Ch.0) - One Type-K Thermocouple

Can you please list some in this way. Thank you!

I am really desperate, I need as many thermocouples to be connected as possible.
