I have a couple of projects that I need to use some relays.
I need to switch a DC load with a DC sig.
Im buying from ebay cause the prices are good. I see alot of DC triggered and AC load relays. I am switching DC loads with a DC trigger. Can I use an AC load SS relay to control a DC load? I would think so, I dont know why they differentiate between an AC load or DC other than maybe an AC relay has some advantages to be used with AC. But a simple DC switching relay might not have the issues that an AC load might.
And Im well within my current needs and voltages. So thats not an issue. Im switching lower voltages, higher current. So the RMS value between an AC relay and a DC relay is not a concern here. They are 230VAC relays and Im switching 24VDC. Current is rated at 40amps and Im switching 20amps max.
Im asking because the availability of DC triggered, AC load SS relays is massive. Pennies on the dollar. Dc-Dc SS relays for my current demand are much higher. Id rather save some money if the AC load relays will work.
Thanks in advance for any help... JR
