Velleman makes quite a few controllers.
Ive been looking and looking. If you would please, post links/schematics to all the known USB relay controllers available right now. Phidgets and IO Warrior are the two most promising for me right now but I would like to see all my options
cool, ill look at my options. What about just being able to drive a 12v relay with one of these boards. It would be really sweet if im able to find a way for the IO Warrior (Link) to just be able to send an impluse to drive a regular 12vdc car relay. I dont really need the relay built in...just a way to drive it.
The phidget's are used mostly in sim and robotic projects, but I'm using them for the sensor data (heat and vibration monitoring). The 0/4 board is the relay board.
yes, ive looked into phidgets pretty heavily. I love how you can just plug in a wide array of sensors and I plan on getting a few very soon but I just need to drive car 12vdc relays. I figure that if I can get normal relays to work with some of these boards then I can have windows/light/a/c/any other kind of accessorry that I want at the touch of a button controlled by my comptuer.
lol i just read the 0/16/16 specs and it says ...
"16 Digital Outputs
These outputs require that an external voltage source supply the power. The outputs can sink up to 30VDC at 2A. This type of output is commonly referred to as "low side switching" The Digital Outputs have a refresh rate of approximately 125Hz."
could that be used to drive a relay?
what do you want to drive with the relay?
I use the U3 from Labjack which is USB and has upto 20 I/O pins available for input, output, frequency counters etc etc
