I looked at the datasheet of the HV2733 on the link posted by RCinFLA.
This would certainly do what you want, but it needs a serial data input.
However, I don't know what it would cost and also, it means that you would need something such as a microcontroller to generate the serial data to drive it.
Alternatively, you could do it using 5 relays as I said before, or you could do it using 11 LDRs illuminated by 11 LEDs.
I don't know if LDRs can withstand 48 volt, you would have to check that.
What determines which input you want to read?
For example, is it done by a counter?
I can post a simple relay circuit for you if you wish to take that path.
A relay has insulated wire wound around an iron core (an electromagnet), when you put a current through the coil, it attracts an armature which moves and causes a set of spring sets to move.
I suggest you do a Google search for "relays" as I expect there will be plenty of information available.
If you have any questions, just ask.
