I have a digital device that responds to programmed triggers and and outputs +3.3vdc 500ma upon the trigger command.
I need to control a 12vdc .08ma LED.
Attempted this using an SSR 5vdc 1A NO (plus 12v supply) to switch the LED (DigiKey Z2521-ND)
Upon the trigger, the relay operates and the LED illuminates, but when the trigger opens, the LED remains on.
The bottom load voltage on this particular SSR is 70v. It that the reason it does not open when the trigger is removed?
Can anyone suggest an SSR that will work properly for this application and is reasonably priced (I need 56 of them)?
