LabVIEW
Connecting Relay to Labview
Solved!
Hello,
I have two pressure transducers that are connected to these Omega meters (Part no. DP8PT-330). From there, I want to output the values from the meter into LabVIEW. I have attached the user manual which shows the pin outputs. Basically, there are three options to wiring: Normally open relay, normally closed relay, and relay common/SSR. Which one of these would be the best to use? Is it possible to get these data points from the meters in LabVIEW without using any DAQ?
If not, I have USB-6001 and NI-9208 available to use. Would either of these work?
I am kind of stuck here, so any input would be greatly appreciated!
Those relay outputs are just for alarms. If you want the actual measurements, you need to communicate with the meters over the USB, RS-232 (option for the meter) or Ethernet (option for the meter). It looks like it uses ModBus as the protocol. You can download the software zip file for this device. There is another zip file inside of that for LabVIEW drivers. Try using that.
