4n33 circuit
I have a computer device that sends a 3.3v dc signal when the computer is actively recording audio. I want to connect this device to a record light circuit that uses a solid state relay that (when activated) sends 120V ac to our On-Air lights.
even thought the solid state relay claims a 3-24V input trigger range I have had problems with any signal lower than 7 volts actually triggering the Solid State Relay (SSR).
I either need to boost the 3.3v to around 8-10v or ...
The Computer device manufacturer suggests using an optocoupler in between my computer and the SSR. I have a 4N33 in my parts bin.
What is the best way to connect the 4N33 to acheive the desired result?
Thanks, Brain Damage
