Thread: Question about relay interface boards

Hey guys, I'm new to the forums and I have a question. I'm looking to incorporate my car's HVAC controls into my car PC setup, and so i'm looking for the best solution for a PC relay interface board. I have heard of people using the Phidget USB relay card to handle digital I/O. This board seems like a good solution, but I'm wondering if I can program and decent GUI for it, etc. Any good digital I/O with decent GUI setups out there? Thanks for the help.
