www.futurlec.com sells an opto-isolated four-relay board that's capable of
switching normal house current (and higher if I remember right). There's a
small area on the board where additional components can be added. I added
four DS2405s there to make a 1wire relay board. The relay board needs 5V
for the logic and 12V for the relays. I think the board was only about $13.

Use e.g. a MOC3023 optocouple with triac output to switch a power triac
e.g.
TIC206D (easy to get) or BTA10 (insulated mounting tab).
http://www.datasheetcatalog.com/datasheets_pdf/M/O/C/3/MOC3023-M.shtml
That datasheet cointains application circuits for 110 and 220V. For 24V,
extrapolate a bit.
Kind regards
