I'm using a CIO-ERB08 8 relay board that has 5V inputs with a Weeder DIO
board. I use a 7805 5V voltage regulator mounted on a small pc board that
is attached to the relay board. A din 37 pin connector on the relay board
interfaces to the digital signals of the DIO. Info about the relay board
is at http://www.omega.com/ppt/ppt.asp?ref=CIO-ERB. I have my DIO at the
MH PC and the relay card at the PA. They use two different power
supplies run at two different locations.

Thanks to several folks for the feedback to my "what relay cards do you
It sounds as though several people are using weeder + the JAMECO universal
relay kit. I've looked at the jameco web site, including the catalog page,
and understand it comes with 8 relays, you can add 8 more, can add LEDs,
The jameco board isn't truly compatible with the weeder board; you have to
put driver transistors in between. This is a doable thing, but if I can
pick a board with driver transistors already on it, in about the same price
range, I'd rather do that. It will make for a cleaner install. Also, the
weeder board will run on 12VDC (really 8 to 25) and the jameco relay board
appears to require 125VAC. I'd like to find boards where everything runs
off of the same power supply, and I lean heavily toward 12VDC as I plan to
get a car stereo power amp module for my audio requirements.
So, I'm still leaning toward a weeder + an eeci RH8 board (www.eeci.com).
The RH8 takes "TTL Level" inputs. I interpret this to be 5v low current
and should be compatible with the weeder outputs.
Any comments? and/or anyone using any other DIO and/or relay boards?
