    Programmable Relay Controller

    Hey guys,
    Me and a partner have been working on what we call a Programmable Relay Controller since May. We've completed a proof of concept prototype and we are very excited with the results. So here is the run down
    It has 8 spdt relay outputs rated at 10 amps with built in 10 amp fuse protection which can be de-rated as required.
    12 optically isolated digital inputs that can be triggered via a +12 or gnd signal
    4 wireless inputs from a 4 button rolling code keyfob
    The current prototype is 4x6 inches but the new board will be 3.5x4.5 inches.
    The new version will also be usb capable and usb powered.
    Now with all of the hardware out of the way.
    The unit is self contained, it does not have to directly interface with a pc for the control algorithim. It is programmed with a language called relay ladder logic which is a graphical object based language. So if you are familiar with relays and their operation it is very simple and intuitive. It is capable of performing integer arithmetic and is equipped with event 40 timers(10ms resolution.)
    Once the user program is written it is then stored onto the PRC via a USB cable and remains resident on the controller, until it is reprogrammed of course.
    The user interface is current under progress but it is going to be a good while before it is ready. All good things take good time I suppose.
    We currently can do custom applications but they are pre-programmed.

    Check out the web site, it explains things in a little better detail. www.iLL-LOGiX.com

    Any ways, I'd like to hear what you guys think.

    Cool
    I've been thinking of someway to make something kinda like this.
    One thing that would be cool is to create a part on there for like a serial (im pretty sure thats the really big one) cable to plug in and then you could control a bunch of stuff from the computer or like have it use a usb controller so you could like roll the windows down from the computer. Or maybe that is on this, i wasn't too sure.
    Any idea how much one would cost?

    We are currently thinking it will fall into the $200 dollar range depending on options.

    Our focus was to eliminate the need for the PC. The reasoning was it is easier for some one to program a device than it is to program an OS application. We can spin a different version of firmware so it would work like an IO device and not a PLC. So the pricing wouldnt change. It would use a modbus protocol which is pretty standard for the industrial controls industry.

    Just a note, the software used to configure one of these will be free.

    If there is enough interest in using this strictly as an IO device I could spin that up in a couple of day. Probably could have something available late January/Febuary depending on how the new hardware layout is testing goes.
