driving a 24v relay/transistor

Started by Chris June 11, 2007
Have you ever thought of using an opto isolator?
I use a LCA710. Rated for 2 amps dc and can handle 24 volts with no problem.
I use a 680 ohm resistor on the input from the basicx.
There are other opto isolators that are cheaper too.

I have to control a few 24v light bulbs using pins on the BX24. I'm
wondering if there is a transistor I can use to power the bulbs
directly . The bulbs draw 208ma.
