I've got a box that's designed to drive an IR emitter
(https://www.electro-tech-online.com/custompdfs/2008/08/5034NIRT20series20data20sheet2.pdf if you're curious).
I'd like to drive multiple emitters (at least 4), and I suspect it doesn't have enough power to do that (haven't been able to test it yet, but the specs say the IR port is "20 mA max rated continuous output" (and 5 V DC max) -- I couldn't find anything that said what I'd need to drive a reasonable IR emitter).
So I guess I need to amplify it. It also says "These sockets are not isolated from C-Bus and must NOT be grounded or connected to a voltage source", so I'm thinking optoisolator? But I'm a software guy, so I don't really know what I'm talking about.
Of course I could stick an IR emitter on it and then buy a $150 4-port IR distribution system... but I figure there's got to be a much, much better way!
