NI PCI-6259 with SCB-68 - Shielded or BNC-2110 - Shielded?

[Naser1363]

Hello everyone,

I want to but a NI PCI-6259 but I don't know do I choses a  SCB-68 - Shielded or BNC-2110 - Shielded connector block?
NI recommended is  SCB-68 - Shielded but I think BNC-2110 - Shielded is user friendly.
NI PCI-6259 require 2 connector block.It has 32 analog input.I think BNC-2110 - Shielded have 8 analog input(AI) so whole of analog input with 2 BNC-2110 - Shielded is 2*8=16.But NI PCI-6259 has 32 analog input.

Would you please tell me about this problem?

 
Best regards

Hello Naser,

Here is some additional information that will be of help to you

The PCI 6259 DAQ card has 32 SE/16 Differential Analog inputs

Now, if you are planning on using BNC 2110, The BNC-2110 is only intended for differential analog input signals

So by using two BNC 2110, you can access the 16 Differential AI channels on your device

Read the Connecting Differential Analog signals section in the BNC 2110 installation Guide that you can find here

The other flip side of using this accessory will be the number of Digital lines that you can access while using this combination

Please read this link for more information on the same:

Hope this helps you

Regards,

Dev

Hello Dev,

Thanks for your reply.

I understand BNC-2110 – Shielded can’t access to all of the 48 I/O, 32 AI and 4 AO of NI PCI-6259.

So do you recommend to me SCB-68 – Shielded?

Can I access to all of the 48 I/O, 32 AI and 4 AO of NI PCI-6259 with SCB-68 – Shielded?

Best regards

Hi Naser,

       You can connect to every input using 2 SCB-68 connector blocks (giving you access to the 32 AI, 48DIO, and 4 AO the 6259 provides).  Page 23 of the specifications lists the pin assignments for the 6259, which is how you'll connect your signals to the SCB-68.  Have a good one!
