Hi All,
I have something of a problem with a project and as my electronics knowledge is more than a little rusty I'm hoping someone can point me in the right direction.
I have an output from a piece of equipment (3.3vdc @ 3mA) which I need to use to switch a 24vdc supply. My initial solution (before I realised just how little current I had to play with) was to use a signal relay, however the current draw is far too high (~70mA).
It has been suggested that I use a transistor switch but I'm not too sure how to proceed with this, or what kind of device specifications I should be looking for.
If anyone here is able to shed any light on this it would be much appreciated!
Thanks
Dan
