Thanks, I think I got it. Basically, 120VAC will work so long as the load it is switching is rated for DC not just AC.The relay won't care. Yes, you can use a relay with a 120 VAC coil or about any coil voltage to switch a 24 volt load. There are a few caveats. Make sure the relay contacts are rated for your load. For example switching a DC voltage is not the same as switching an AC voltage. So if switching 24 VDC make sure your relay contacts are rated for your DC voltage and the load current.

The control voltage is 120VAC switching 24vDC. I am trying to find a relay that will work for that. To provide more information, I am using a PID that will output 120VAC. I need to use that to trigger a 24VDC solenoid valve.You didn’t say whether the control voltage and the switched voltage is AC or DC.
The relay coil also must be appropriately rated for AC or DC, whichever you are using. A 120VAC relay will go up in smoke if you give it 120V DC.
You should not have any problem finding one, any electronic supplier will have them, Digikey, Mouser etcThe control voltage is 120VAC switching 24vDC. I am trying to find a relay that will work for that.
Yes, I just need a hardwired relay. Again, pretty new to this. I am finding plenty of relays that take a DC load in but then the spec says 240VAC for the output or voltage that it is switching. What is throwing me off is say AC and I want to switch a DC load on the outbound side. Will this work even though it is alternating current. If not can you link me to right type of relay that might work for my application. Thanks for all the help.You should not have any problem finding one, any electronic supplier will have them, Digikey, Mouser etc
Printed circuit mount or hardwired, presumably you want the latter!
It is a DC solenoid!!The five amp contacts are to handle the solenoid inrush current with an adequate safety margin.
Or a handful for a couple of $$s at an auto wrecker.s. Automotive relays and their sockets are readily available online and any automotive parts store. Yes, they cost a little more
