Hi,
I have 4 solenoid valves 120VAC, working at 6.1 watts, requiring 0.05 amps. I want to control them from labVIEW via a DAQ hardware device.
My doubt is if there are hardware devices out there which give that much output to trigger a solenoid valve ON/OFF?
If NO, is there any way that I can achieve this?
Thank you.

Have you tried a digital output controlling a relay?

Thank you for the reply Jim.
I haven't tried it. Can you please explain in detail.

A digital output device (DO) is controlled by your PC to turn a DC voltage on and off. A relay is a switch that uses an electrical input, typically low voltage but not always, and usually low current (like from a DO) to switch a higher voltage and/or current signal - like your 120VAC to control your solenoid.

hi
just use a relay circuit to switch any type of inductive load .you can get a lot of relay circuits from internet ....if not found then i will try to send u....
bye bye

Solid state relays (SSR's) are a good way to go, they can trpicially be driven by most DIO lines and create no inductive spike when turned off. They also come in zero-crossing turn on/off styles for a clean power on/off transition on the AC side.
If you do end up using a coil based relay, be sure to a reverse biased diode (1N4004 work well) to prevent damage to the DIO line when turned off (aforementioned inductive spike).

Hi,
I have the exact same problem as the original poster of this thread. Does your offer stilll stand? I did search the internet for relay circuits and did not find any circuits relevant.
Would you be willing to try to send me circuit diagrams of a relay triggering a solenoid?
You would be helping a college student project!!!
🙂
Thanks
