Hello everyone, Hope You are good.
I am Using 6008 NI DAQ To Control 24v valve to switch on/off
When I connect the digital pin from the DAQ Directly to the base of the transistor The valve goes on .. and i can't control it
so my question is what is the right connection Should i use on 6008 NI to control the valve
and do i need resistance between the pin and the base .. and if the answer if yes what is the value of the resistance should i use?

Your question isn't a LabVIEW question, but rather an Electronics Circuit question, what circuit (presumably a 1-transistor circuit) should you use to get a TTL signal to drive a 24v relay. Maybe "Ask Google"?

For questions specific to the NI USB-6008 you can check out the device's User Guide or Device Specifications, which has the device pinout on the last page.
