Re: Homevision Relay boards ... Interested?

["Simon Coates" <ecolume@xxxxxxx>]

Hi Phil,

I got an RCS X10 relay board from Worthington Distribution -
http://www.resconsys.com/Products/relay/xr16_channel.htm
They are available as latched and as momentary outputs.
Benefits are: simple installation, 16 DPDT relays, fairly cheap, nice
enclosure and it doesn't take up any of the valuable HV outputs.

Simon

PS. I've got an occupancy PIR and I'll post it to you on Monday :o)
