SCB 68 connections

[tronoh]

Dear Sir

I am using NI PCI 6281 along with SCB-68. I want to collect data from a sensor which has BNC connector. My SCB 68 has no BNC port and I can only connect bare wires. What I should do? If I remove the BNC plug from the sensor wire and connect bare sensor wires to SCB 68 then will it be OK? or it will effect on the measurement?

Kind Regards

Urfee

You may get a little more noise when going through the connector block than you would if you had a direct BNC connection on the DAQ.  But it shouldn't be enough to matter.  I would just cut the end off of the BNC cable to connect the signal and ground in the terminal block.

But if you are really worried about it, NI does have some DAQ boards with BNC connection.  I haven't looked in a while, but they tend to be on the high end.
