Problem with K2633

Hi!

I’m a big NOOB in all this stuff+I’m not Englishman so it’s quite difficult to understand all instructions. And so, where is my problem?

I have to do school project and for that i have bought K2633 (relay card) and K8055 USB board, BUT I don’t know hot to connect them. For my project i need something like this: Using K8055 I can control relay card with my PC. But it just doesn’t work. Ok maybe the main problem is that i even don’t know how to properly connect relay card to power. Can anyone show me some simple diagram where in a easy way is explained connection with power and also with USB board. And how can I connect something to relay? For example 4 simple LEDs.

Please, i need help!

The connection is very easy:
Connect external 9V power supply to the VDC connector of the relay card (note the right polarity).

  • Connect the inputs 1…4 of the relay card to the digital outputs of the K8055.
  • Connect the GND terminal of the relay card to the GND of the K8055 card.

Then just control the digital outputs of the K8055 from the software and you should get the relays to ‘click’ and the relay output will change state. (The C and NC contact will open and C and NO will close.)

Connected everything, tested everything… works perfect!! Thanks!

And now… programming stuff. If i want that everything switches automatically i need to make my own program right? Too bad that my knowledge is … well i don’t know anything in programming also. How should i start?

But anyway, big thanks, VEL255!!

You may start by downloading the free Visual Basic 2008 Express Edition from microsoft.com/express/download/

is it necessary to wire the clamp of K8055 to the ext. power(+) of relay card? any inductive issues?
otherwise I connected inputs of relay card to digital outputs of K8055 and GND of relay card to GND of K8055.
