What do I need for analog output? Newb alert... *help*

[Ralph@NES]

Hello all.

I've got the following:

SCXI 1001 chassis

1349

1102/b/c with SCXI-1303 terminal block

1180 with 1302 terminal block.

I'm aware that analog output voltage must be sent throught the 1180.  Are there analog terminals on the 1302 or is that all input channels?

Am I missing a needed component?

*help*

Ralph,

The 1302 is a breakout terminal block for the 1180 which is just a feed through module. This means that it gives you direct access to the 50 pin connector on the back end of your SCXI chassis (the 1359). Now the 1359 is just a 68pin to 50 pin converter for connecting your DAQ card to your SCXI chassis. So the upshot of all of that is the 1302 is going to give you access to lines from your DAQ card. Some of those are going to be input lines, others outputs, etc. Take a look at this Knowledge Base about the subject, and follow the links in the KB. Ultimately you are going to have to look at what DAQ card you have and the pinout translation between the 68-50 pin converter (the 1359) to determine what pin is what.

I hope that has helped (more then confuse =P ). Feel free to post back if you have questions about anything I mentioned here.

That listed the pinouts for the 1180, which helped.  Along with what you posted I think I can get all of this to make some sense.

Thanks!

Glad to help out, looks like you are on the right track now, good luck with everything!

Thanks very much...

Wondering, since I have your attention, does NI make any sort of breakout or extension that's a D/A converter?  I'd like to eventually control multiple relays this way, rather than just two via analog and I'm hoping to do it within the confines of the SCXI setup we've got.

Ideas?  Existing product?

You could also use some of the digital lines that are available on the SCXI-1180 and you should probably try to use those when controlling relays.  You will likely need more power than the DO lines can handle, so you may need some external amplification.

Your best bet is to use a SCXI switch matrix or relay driver as I pointed you to in your other thread:

[Ralph@NES]

Relay drivers sound exactly like what I'll need.

Can you explain the difference between one-wire and two-wire setups?  Is the single wire unit just using a common ground?

[Ralph@NES]

I'm looking at the 1167 relay driver right now.  What more hardware would I need to make that work with my 6221/1349 and modules installed?  Can that be added in a chain to what I have?  And is there a breakout or terminal connector for it that's separate?

It sounds like you've found what you need.  The best step to take now would be to contact NI and speak with one of our Technical Representatives and they can point you towards the best solution for your needs:

Communicating with Robin in Rochester/Buffalo area about that right now.  🙂  Thanks!

Now I just need to hit the LabVIEW forum and see what I can do about this silly analog output channel that's giving me fits.  Thanks!
