Need help with opto-interrupt switch
Need help with opto-interrupt switch
(OP)
Hi all,
I am using a 12vdc power supply (15.5vdc measured). I would like to use it to drive THIS optical interrupt switch which would then trigger THIS solid state relay (G3VM-2).
1) Are these two components nicely compatible?
2) If they are compatible, how do I wire them up and what other stuff would i need?
3) Am I even asking my question in the right forum?
Any help will be greatly appreciated.

RE: Need help with opto-interrupt switch
Let’s look at the photo-transistor version, -031. You put 20mA into the LED and get 0.3mA out. Now 0.3mA x 1K only gives 0.3V swing. If you put the resistor up to 20K to get a reasonable output swing the delay will increase from the 15µs quoted for a 1k load resistance, probably by a factor or 20x.
