RE: Relay Control

["Phil Harris" <phillip.harris1@xxxxxxx>]

Hey guys ... don't know whether this would be appropriate but I was
shown a relay system that Li had up and running just the other week.

He had a separate controller PCB and 8 relay board and I was suggesting
that the controller board be extended to handle two relay boards (16
relays). He was talking about switched on/off operation plus also
momentary working. The controller board that I saw was an X10 board but
since its separate to the relay PCB then other interfaces should be easy
enough to run up if the requirement is there. (Serial, parallel, 1-wire
etc.)

I have no idea on pricing or how close it is to being a saleable product
but maybe if there's enough interest here then Li might have more
information...
