3.3v to 24vdc

3.3V to 24V relay/contactor.

I would design a controller system by using FPGA or 8051 in order to control devices with +24V.

My quastion is:
which ICs(relays/contactors) you recommend which is enables by +3.3V???
 

for simples cct you need only transistor... read about transistor as a switch..
 

if you need more than 1 i would preffer ULNxxxx which are darlingtn switches, check specs which voltage you need

Why not use ULN2003 or ULN2803?

But my 24V is AC supplied from AC transformator.
so what do you suggest?
 

you mentioned +24v in your first post, it implies 24v DC. Also i think that your relay is DC type (more common) so just use 24v DC
