Solid state relay help

Post by lamby422 »

I need a SSR that is normal open yet has an input tigger of 800-900mV and can handle 12 to 14VDC

My scenario is that i have a pre built circuit which has an led onboard the wen activated sends out 900mV i would like this to trigger a relay that will then allow 12-13.8VDC to another circuit i have that has a 12VDC led with 2A no more than 5A that is visible in another location

Suggestions,help

How much load current does the relay need to handle?

Sorry, you did say that in post 1, but symbol for Ampere is "A" not "a". ( I did not recognize that you where talking about load current.)

Have you tried www.digikey.com ? Or, www.jameco.com when they recover from network problem.

Be sure to look for a DC relay. An AC relay could use triacs internally and not release/switch off when trigger signal ends with a DC supply..
