RS232 controlled 120VAC switch

I need to provide a method to automate testing of Uninterruptable power supplies (UPSs). I want to be able to cut off power programmatically over a serial RS232 connection.

The module must accept 120VAC as power, then switch a 120VAC standard wall receptacle using an RS232 transfer (eg. ACSII 1==switch_on 2==switch_off)


I have searched long and hard for such a simple device, and found nothing.

Any ideas on what company might be selling such a thing would be greatly appreciated.

Thanks,

Travis,

Check out www.blackbox.com , they have some Out-of-Band Management equipment. The unit that seems to fit your need is M/N SW1030A. We use their equipment and find it to be reliable.

Good luck,

Bob

There are some `home automation' systems that should be able to do that... don't know how long they'll last in an industrial setting, though, and I don't have any personal experience with them. The protocol is called x10.
