I've got a couple of watchdog modules from Brentek (http://brentek.com) that I think would do what you want. The ones I have are WDT5 units, which plug into an Opto22 rack. They have a variety of other form factors though. It looks like they show up on ebay too.

Losing our local Radio Shack I now have to order online, so if I can, I may as well order the ready-made thing if its available. It should have an output buffer that is polarity selectable, and the output should be robust enough, and back emf protected, so as to run a P&B multipole "socketted" Ice Cube relay, which can then run even bigger stuff. One such application would be a couple of the multibreak T-Bar power relays for the soft start and power circuits I mentioned controlling the other day. Does anyone make such a critter? Thanks.
