Connect Solid State Relay to DAQ to output voltage

[andge]

Hello,

I am very inexperienced at LabVIEW and need help writing a code/utilizing my DAQ device.  I am trying to control a solenoid valve using a solid state relay as a switch.  I would like for the relay to be charged for a prescribed time period that I want the solenoid valve to be opened for.  I need to send some sort of square wave of voltage to the relay using a SCB-68A.  Any help???

This link has come information with programming for DAQ using the DAQmx driver: http://www.ni.com/white-paper/5438/en/

LabVIEW also ships with helpful DAQmx examples, which can be found in LabVIEW under: Help>>Find Examples...>>Hardware Input and Output>>DAQmx

This has information on setting up your DAQ device: http://www.ni.com/gettingstarted/setuphardware/dataacquisition/

What DAQ device are you using? How is the solid state relay controlled?

I am working on a project where I need to close the solenoid valve (24DCV) at a different rate of time (variable closer time). It needs to be very fast (at least within 50ms). I am using NI DAQ: USB-6211. Which relay should I use? Will digital relay timer work? This is how I am planning to implement the circuit. Also which flyback diode should I use (25A)? Looking forward to your suggestions.

First you should start a new tread vs talking over a tread from 2013. You might not get the help you need if you go to an old tread for help.

You can use the digital output to control any relay that has a 5VDC control side. The relay you choose should be based on research. If you look up relays you should be able to find the on time. There are many that have very fast on response times. You will also need to decide if you want solid state or cube relay. Solid state relay is never fully open or fully closed. If you have a little leakage would that be OK. If not then use a cube relay.

Things that you need to look for in the relay you choose:

• Control side voltage
• output side voltage
• Response time
• Single throw\Double throw
• Solid state\Mechanical relay
• Load (amps)
• Activation load control side (If you get one that that takes more load than you have on your digital output it will not activate)

I hope this helped

This thread contains two different issues, one from 2013 and one from 2019. Both are answered already.

If you have a specific question, I would recommend to start a new thread and explain the problem in detail.
