Hey guys! New to the forum, great site!!

Here's my ?. I work with a tracer summit system daily hooking up tcm's, new voyagers, etc.. Just out of curiosity, is there any similar type of system that could be set up for home use?? Without a huge pricetag. I've heard about I/O cards that can be installed in a pc, but I haven't found anything that could use 4-20mA analog and/or 24v binary inputs (maybe even outputs). Then comes the software problems.

Just thinking it'd be cool to jump on the comp and see my sup/ret air temps, strip heat status, and other assorted things. Thanks in advance!
