Hello everyone. I'm looking for a small plc that will sound off an alarm at various currents for an open path gas detector. This plc has to
be as cheap as I can get it. If antone can help me I would greatly appreciate it. Thanks alot! My email address is: [email protected]
Lots of options out there. Here is something from a few weeks ago.

I am not sure if you need analog or not. If not, then the Allen-Bradley Pico Controller is pretty cheap. The 1760-L12BWB is about $150. It has 8 digital inputs and 4 digital outputs. It has it's own interface for entering the logic or you can pay $60 for the cable and download the software for free. I have one in my office that I have played with. Here is the web link:
